2023 Q49
The period of the discrete-time signal x[n] described by the equation below is N = ____________ (Round off to the nearest integer). x[n] = 1 + 3sin($\frac{15\pi}{8}n + \frac{3\pi}{4}$) - 5sin($\frac{\pi}{3}n - \frac{\pi}...

2023 Q50
The discrete-time Fourier transform of a signal x[n] is X($\Omega$) = (1 + cos$\Omega$)e$^{-j\Omega}$. Consider that x$_p$[n] is a periodic signal of period N = 5 such that x$_p$[n] = x[n], for n = 0,1,2 = 0, for n = 3,4...
