Matlab m-file code writing problem. You are given signal x(t) = 2* exp(-2t) * sin (2 t). You want to plot x(t) vs. t for t ranging from 0 to 10 sec with 0.01 second increment. a. Find amplitude of signal x(t) [i.e., 2* exp(-2t)) at t=0 and t = b. Find frequency and period of this signal c. Write a Matlab codes to generate t vector and corresponding x vector and plot (t vs. x). We want to put the range of x axis 0 to 12, label 'Time (sec)' and the range of y axis -2 to 2 and label 'x(t)'. In script editor write and run the .m file and make sure it is showing the plot you intended, then copy back the code in space below.

For the following function = x + xx + XX3 (a) Optimize the gate level design by using only 2-input NAND gates. Then, count total number of transistors. (b) Design CMOS circuit that minimizes the number of transistors. Then compare the number of transistors and its critical path delay with that of circuit in (a). (c) Optimize the design using FPGA utilizing 2-input LUT's. How many cells of FPGA are used? (d) Implement it using 2-to-1 multiplexers only. It needs to select optimized one after investigating all possible implementations.

What design pattern can be applied to the static program analysis software you described in the previous problems? What software design problem can this design pattern solve?here's the analysis:Scope statement:The software is designed to perform software analysis. It is done without code execution. The code will be in static mode. The analysis can be performed on source or object code based on the requirements. It is done so that programming errors, violations, vulnerabilities, etc. can be detected.The milestones and constraints related to this software are based on documentation, structure, perspective, etc.Characteristics:It should be able to debug the code before its execution.It should be able to investigate code keeping certain rules into consideration.It should detect the issues very early on so that cost of fixing them is less.It should also cover all the potential execution paths.UICF 2,300 2DGA 5,300 3DGA 6,800 DBM 3350 CGDF 4950 PCF 2,100 DAM 8,400 Estimate line of code 33,200 Organization produces 450 loc/pm Burdened labor rate - $7,000 per person-month Using the data noted in the problem = 33,200 Loc/450 Loc PM = 73.7 PM Cost = 73.7 * $ 7000 PM = $515900 (approximately)

Which of the following is not a true statement regarding MAC addresses?There are more possible unique MAC addresses than there are unique IP(V4) addresses, however there are more unique IPV6 addresses than unique MAC addresses.A link-layer hardware device (e.g.. NIC) has a permanent and constant MAC address irrespective of which network it attaches toWhen sending data to a host in an external network, we can use either the IP address or the MAC address to specify that host in our request.MAC addresses are used to send data from one node to another within a single subnet.
