IRA 4. The amplitude spectrum of the signal x() is shown as follows: 1801 2 Answer: 24 -400 swer: -200 Determine the Nyquist rate to sample x(1). (a) 200 Hz (b) 300 Hz (c) 400 Hz (d) 600 Hz (e) 800 Hz 0 200 (a) the frequency of x(1) must be 213 Hz (b) the frequency of x(t) must be 500 Hz (c) the frequency of x(t) must be 1 kHz (d) the frequency of x(t) must be 2 kHz (e) none of the above 400 IRA#6_5. The signal x(t) is sampled with a sampling frequency lower than the Nyquist rate to obtain x[n]-cos(213nr/500). If the sampling frequency is 1 kHz, then f(Hz)
