Question No. 2

What is the Nyquist sampling rate for each of the following signals?

a.     A low-pass signal with bandwidth of 150 KHz?

Solve:

Low  – pass signal f_l = 0 Hz

F_h  = f_l + BW

F_h  = 0 + 150 KHz

F_h  = 150 KHz

Nyquist Sampling rate = 2 x 150 k

Nyquist Sampling rate = 300000 sample per second

b.     A band-pass signal with bandwidth of 250 KHz if the lowest frequency is 100 KHz?

Solve:

Band pass signal  f_h  = f_l  + BW

Band pass signal  f_h  =100k + 250k

Band pass signal  f_h  = 350Khz

Nyquist Sampling rate = 2 x 350 k

Nyquist Sampling rate = 700000 sample per second
