engineering recuitment GATE EE 2023-24 Test Series Signals and Systems Sampling Sampling Theorem and Nyquist Rate
A signal x(t) having a frequency component up to 20 kHz is sampled at a rate of 38 kHz and reconstructed through an LPF with unity gain and a cutoff frequency of 25 kHz. Which of the following statement is true?
1
The signal can be reconstructed only for frequencies |f| < 18 kHz
2
The signal can be reconstructed completely
3
The signal can be reconstructed only for 18 < |f| < 20 kHz
4
None of these
