Question

A signal is band-limited between 2 kHz and 2.1 kHz. If the signal is sampled at 1750 Hz, the baseband signal will lie between?a. 00 and 650 Hzb. 750 and 2000 Hzc. 100 and 110 Hzd. 250 and 350 Hz

Answer 1

duhhhhhhhhhhhhhhhh

Step-by-step explanation:

duhhhhhhhhhhhhhhhhhh

Answer 2

Explanation: 100 and 110 Hz

Here fL=2kHz, fH=2.1kHz, B=0.1kHz, fL=2kHz,

n≤fH/(fH-fL)

n≤(2.1*1000)/((2.1-2)*1000)

n≤20

2fH/n ≤ fs

(2*2.1*1000)/20 ≤ fs

210≤ fs
