An analog signal consists of three sinusoids with frequencies3.1 KHz, 4.82 KHz, and 5.64 KHz. The signal is sampled at asampling rate of 32 KHz producing the Discrete signal x(n).
Determine the normalized frequencies in x(n).
A signal x1(n) is produced by inserting a zero betweensamples of x(n). Determine the normalized frequencies inx1(n).
