What is the convolution sum of x[n] = u[n+ 2] and h[n] = [n 1] y[n] = x[n] h[n] a) u[n+ 1] b) u[n] c) u[n 1] - d) u[n-2] e) None of the above

Answers

Answer 1

The convolution sum of the sequences x[n] = u[n + 2] and h[n] = [n 1] results in y[n] = u[n + 1]. This means that option (a) u[n + 1] is the correct answer.

The convolution sum is a mathematical operation that combines two sequences to produce a new sequence. In this case, x[n] is a unit step function shifted to the right by two units. It is 0 for n < -2 and 1 for n ≥ -2. The sequence h[n] is defined as [n 1], which means it has two elements: n and 1.

To find the convolution sum, we need to flip h[n] and slide it across x[n], multiplying the corresponding values and summing them up. Since h[n] has two elements, the resulting sequence y[n] will have three elements. By performing the convolution sum, we find that y[n] = u[n + 1], which means it is a unit step function shifted to the left by one unit. It is 0 for n < -1 and 1 for n ≥ -1.

In summary, the convolution sum of x[n] = u[n + 2] and h[n] = [n 1] is y[n] = u[n + 1]. This means that option (a) u[n + 1] is the correct answer.

Answers

A contractor has a job that should be completed in 100 days. At present, he has 80 men on the job and it is estimated that they will finish the work in 130 days. Of the 80 men, 50 are each paid ₱120.00 a day, 25 at ₱180.00 a day, and 5 at ₱250.00 a day. For each day beyond the original 100 days, a contractor has to pay ₱500.00.

liquidated damages.(a) How many more men should the contractor add so that he would complete the work on time?In the first case, we see that the contractor already has 80 men and they are working for 130 days to complete the job. So, we can use the following formula to determine the additional number of workers required to finish the work in 100 days.

b) If of the additional men, 2 are paid ₱180.00 a day, and the rest at ₱120.00 a day, would the contractor save money by employing more men and not paying the fine Let’s assume that the contractor adds 440 workers, of which 2 are paid ₱180.00 a day and the rest are paid ₱120.00 a day.

The total cost of the new workers is, therefore, ₱9600.00 + ₱4500.00 + ₱49800.00 = ₱63,900.00.The cost of liquidated damages would be calculated as follows: $$LD = (130-100) \cdot 500 = ₱15,000.00$$.

Therefore, the contractor would save money if he employs more men and not pays the fine. The contractor’s savings would be:$$Savings = LD - Additional cost$$$$= 15000.00 - 63900.00 $$$$= -48900.00$$

Thus, we can see that the contractor would save ₱48,900.00 by employing more men and not paying the fine.

Science and technology are the driving forces behind today's modern medicine, allowing us to identify and treat a range of medical problems. X-ray technology has had a significant impact on medicine, and it is commonly used to diagnose various diseases, making it an essential tool for hospitals.

Despite the advantages, the scarcity of portable X-ray machines creates difficulties for hospital employees, including a dispute between the emergency room and the operating room staff at Ew Wakefield Hospital. There is only one portable X-ray machine available at Ew Wakefield Hospital.

The conflict between the emergency room and the operating room staff is a result of scarcity. Both departments require ready access to the X-ray machine. Scarcity can generate rivalry, competition, and conflict when people and organizations compete for the same resource.

Also note that mreq is an active low signal )

Answers

The CE signal is generated by the AND gate that takes the MREQ control signal from the CPU as input and produces a low output if the memory address range is from $4000 to $4FFF.

To design a 4K x 8 memory system with high-order interleaving using 2K x 8 SRAM chips for a computer system with an 8-bit data bus and a 16-bit address bus, we need to use two 2K x 8 SRAM chips in combination. This will create a single 4K x 8 memory unit with a total capacity of 4096 bytes.

To generate the CE signal, we need to use logic gates. The CE signal should be active low, and it should be active only if the MREQ control signal from the CPU is also active. The memory address range for this subsystem is from $4000 to $4FFF.

Here is the logic to generate the CE signal:

1. Connect the MREQ control signal from the CPU to the input of an AND gate.
2. Connect the output of the AND gate to the CE input of both SRAM chips.
3. Connect the address bus to the address inputs of both SRAM chips.
4. Interleave the address bits to ensure high-order interleaving.

For example, if the address bus has bits A15-A0, connect A15, A13, A11, A9, A7, A5, A3, and A1 to the address input of one SRAM chip, and connect A14, A12, A10, A8, A6, A4, A2, and A0 to the address input of the other SRAM chip.

5. Connect the data bus to the data inputs and outputs of both SRAM chips.

The CE signal will be active low when the MREQ control signal from the CPU is active and the memory address range is from $4000 to $4FFF. All interconnections and signal names for the CE logic should be clearly labeled.

Therefore, This output is connected to the CE input of both SRAM chips to ensure that they are activated only when the CE signal is active. The address bus is interleaved to ensure high-order interleaving, and the data bus is connected to both SRAM chips for reading and writing data.

If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

What we need to perform?

We need to perform a two step process to obtain the maximum shear stress on the shaft. For the solid shaft,

P=2×pi×N×T/60 or T=60×p/2×pi×N

Where P=power transmitted by the shaft=50×10³W

N=rotation speed of the shaft in rpm=730rpm

Pi=3.142

T is the twisting moment

By substituting the values for pi, N and P, we get

T=654Nm or 654×10³Nmm

Also, T=pi×rho×d³/16 or rho=16×T/pi×d³

Where rho=maximum shear stress

T = twisting moment=654×10³Nmm

d= diameter of shaft= 40mm

By substituting T, pi and d

Rho=52Mpa

b. For a hollow shaft, the value for rho is unknown

T=pi×rho(do⁴-di⁴/do)/16

Rho=T×16×do/pi×(do⁴-di⁴)

Where

T= twisting moment=654×10³Nmm gotten above

do=outside shaft diawter=40mm

di= inside shaft diameter =30mm

Pi=3.142

Substituting values for pi, do, di and T.

Rho=76Mpa

Therefore, If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

What is Coulomb's Law?

This question can be solved using Coulomb's Law.

Coulomb's Law states that the force of attraction or repulsion between two charged particles is given by the equation F = k*q1*q2/r^2,

where k is the Coulomb Constant (8.99 x 10^9 Nm^2/C^2), q1 and q2 are the charges of the two particles, and r is the distance between them.

First, we need to calculate the electric field strength at each of the given distances (1.0 cm, 2.0 cm, and 3.0 cm).

To do this, we can use the equation E = k*q/r^2,

where k is the Coulomb Constant (8.99 x 10^9 Nm^2/C^2), q is the charge of the rod, and r is the distance between the rod and the point of interest.

For E1, we can calculate the electric field strength at 1.0 cm to the right of the rod on the left as follows:

E1 = 8.99 x 10^9 Nm^2/C^2 * 12 N/C / (0.01 m)^2

= 8.99 x 10^11 N/C

= 8990 x 10^6 N/C

= 4800 N/C

For E2, we can calculate the electric field strength at 2.0 cm to the right of the rod on the left as follows:

E2 = 8.99 x 10^9 Nm^2/C^2 * 12 N/C / (0.02 m)^2

= 4.495 x 10^11 N/C

= 4495 x 10^6 N/C

= 2400 N/C

For E3, we can calculate the electric field strength at 3.0 cm to the right of the rod on the left as follows:

E3 = 8.99 x 10^9 Nm^2/C^2 * 12 N/C / (0.03 m)^2

= 2.997 x 10^11 N/C

= 2997 x 10^6 N/C

= 0 N/C

Therefore, the electric field strengths E1, E2, and E3 at distances 1.0 cm, 2.0 cm, and 3.0 cm to the right of the rod on the left, along the line connecting the midpoints of the two rods are 4800 N/C, 2400 N/C, and 0 N/C, respectively.

Answers

The total wall area that needs to be insulated of the home with 8’ ceilings measuring 42" x 30" and window and door openings approximately 125 ft² can be found out as follows:First, we need to convert 8 feet into inches as follows: 8 feet x 12 inches/foot = 96 inches.

Therefore, the area of one wall can be calculated as follows:Area of one wall = Length x Height= 42 inches x 96 inches= 4,032 square inches= 28 square feetSince there are four walls in a room, the total area of the walls can be calculated by multiplying the area of one wall by.

Therefore:Total wall area that needs to be insulated = Total area of the walls – Area of the window and door openings= 112 square feet – 125 square feet= -13 square feetSince the total wall area can't be negative, there might be a mistake in the given values.
