Question
nyquist criteria sates that original signal can be reconstructed by passing samples through a Select one:a. LPF with cut off fmb. HPF with cut off fmc. HPF with cut off fsd. LPF 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. High Pass Filter (HPF) with cut off frequency fm c. High Pass Filter (HPF) with cut off frequency fs d. Low Pass Filter (LPF) with cut off frequency fs
The correct answer is:
d. Low Pass Filter (LPF) with cut off frequency fs
The Nyquist-Shannon sampling theorem states that a signal can be perfectly reconstructed from its samples if the sampling frequency is greater than twice the maximum frequency of the signal. In this case, the samples are passed through a Low Pass Filter with a cut-off frequency equal to the sampling frequency (fs) to reconstruct the original signal.

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
