What happens when you increase the sampling frequency?

When the sampling rate (Fs) is increased, the distance between the maximum frequency content Fm and Fs/2 will increase. This increase in the gap between the maximum frequency content of the signal and Fs/2 will ease requirements on the transition bands of the anti-aliasing analog filter.

How does sampling rate affect SNR?

for the same wordsize, higher sampling rate increases the SNR (within a fixed bandwidth) by 6 dB or 1 added bit of resolution for every two octaves of sample rate. and that's without noise-shaping. toss in noise shaping and you get better than 3 dB increase in SNR for each doubling of sample rate.

How does sampling frequency affect signal?

Sampling rate determines the sound frequency range (corresponding to pitch) which can be represented in the digital waveform. The range of frequencies represented in a waveform is often called its bandwidth.

How does sampling rate relate to frequency?

sampling frequency. The sampling frequency (or sample rate) is the number of samples per second in a Sound. For example: if the sampling frequency is 44100 hertz, a recording with a duration of 60 seconds will contain 2,646,000 samples.
