Question
nyquist criteria sates that original signal can be reconstructed by passing samples through a Select one:a. LPF with cut off fmb. LPF with cut off fsc. HPF with cut off fmd. HPF with cut off fs
Solution
The Nyquist criterion states that the original signal can be reconstructed by passing samples through a:
a. Low Pass Filter (LPF) with cut off frequency fm b. Low Pass Filter (LPF) with cut off frequency fs c. High Pass Filter (HPF) with cut off frequency fm d. High Pass Filter (HPF) with cut off frequency fs
The correct answer is:
b. Low Pass Filter (LPF) with cut off frequency fs
The Nyquist criterion, also known as the Nyquist-Shannon sampling theorem, states that a signal can be perfectly reconstructed if it is sampled at a rate at least twice its maximum frequency (fs). Therefore, to reconstruct the original signal, the samples should be passed through a Low Pass Filter with a cut-off frequency equal to the sampling frequency (fs).

Nyquist Theorem is The sample rate is the number of times the sample is taken.In order for a computer to work with audio waves, they must be converted from analog to digital form.For lossless digitization, the sampling rate should be at least twice the maximum frequency response.The higher the sample rate, the more samples that are taken and, thus, the better the quality of the digitized audio1.1 and 22.1 and 33.34.1
