Q1] Answer the following: (a) Find the period of the DT signal: $x(n) = 4sin(\frac{8\pi n}{3} + \frac{7\pi}{8})$ (b) Check if the CT signal x(t) is periodic, if so, find the period: $x(t) = cos(5\pi t) + cos(60\pi t)$ (c) Check if the signal $x(t) = (1+t^3)cos^3(10t)$ is even or odd.

Q1] Answer the following:
(a) Find the period of the DT signal: x(n) = 4sin((8π n)/(3) + (7π)/(8))
(b) Check if the CT signal x(t) is periodic, if so, find the period: x(t) = cos(5π t) + cos(60π t)
(c) Check if the signal x(t) = (1+t^3)cos^3(10t) is even or odd.

Step 1

Step 1: To find the period of a discrete-time (DT) signal, we need to find the smallest positive integer N such that x(n) = x(n+N) for all values of n. Show more…
