GATE 2024 Signal & System Foundation Quiz 28

A discrete time signal x[n] is given as

x[n] = 6 u[n + 1] – 3u[n + 3]

which of the following is/are correct.

Suppose we are given the following information about a signal x[n].

1) x[n] is a real and then signal.

2) x[n] has period N = 10 and Fourier coefficient a_K.

3) a₁₁ = 5

4)

Let x(n) = A cos (Bn + C). Then find the value of A + B + C =

If x(t) is a real signal then power of the signal x(t) can be represented as, (where x_e(t) is even part and x_o(t) is odd part of the signal x(t))
