Question 9 A signal X(t) = 5-cos 10mt is sampled at the Nyquist rate, starting at t= 0. What is the z-transform of the resulting discrete-time signal x[n] ? The answer is numeric; give your answer to 3 decimal places. (this is called critical sampling, and is not suitable for signal reconstruction)

Given the continuous-time, continuous-amplitude signal waveform x(1) -3 sample at discrete values of time and plot the discrete-time signal x[n]. Also, extract the even and odd parts of x[n]. Please show the complete and detailed solution. Thank you

(a) Consider a discrete signal, x[n] = { 1, 2, 3,4,5}. Analyze the signal transformation process involved in the following equations. Then, write the answer in numerical representation form. i) k[n] = 0.5x[n+ 1] + 3u[n] – 3u[n – 2] ii) p[n] = x[-n – 1] – 3tri 3

Describe the role of transfer functions in modeling linear time-invariant systems. How can they be used to represent the relationship between inputs and outputs in such systems?

One of the following is a periodic DT signal x[n]: Select one: O a. all of the given options b. sin (2 pi? n/17) O c. sin(2 pi n / 17) O d. sin(2 n /17)
