Question

1) Select the sampling rate as 10000 Hz (i.e. 10 kHz), and the number of samples as 50000 (i.e. 5 sec). What is the Nyquist frequency when sampling at this rate

Answer 1

5 kHz

Explanation:

Sampling rate of a data is the number of times it can acquire a sample of an input signal per second. The Nyquist rate is the minimum sampling rate that can be used to represent a given signal.

The nyquist rate is gotten by dividing the sampling rate by 2, it is given by the formula:

Nyquist rate = sampling rate / 2

There are 50000 samples in 5 seconds, the sampling rate = 10 kHz (50000/5)

Hence, the nyquist rate = 10 kHz / 2 = 5 kHz
