Question

The sampling frequency of a signal is Fs = 2000 samples per second. Find its Nyquist interval.

(a) 0.5 sec

(b) 5 msec

(c) 5 sec

(d) 0.5 msec

The question was asked in a national level competition.

This intriguing question originated from Sampling topic in portion Sampling Theorem of Signals and Systems

Answer 1

Right answer is (b) 5 msec

The explanation is: Given Fs = 2000 samples per second

Nyquist interval, T = \(\frac{1}{F_s} = \frac{1}{2000}\) = 0.5 msec.
