What are the effects of sampling rate?

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.

What happens when sampling rate is too high?

If the rate of samples is too high the system may not be able to process them fast enough - it runs out of processing time.

Does sample rate affect frequency response?

Sample rate affects the frequency response of the final recording or sample; the highest frequency that can accurately be sampled is 1/2 the sample rate. In general, the higher the sample rate, the better the sound quality.

How does sampling frequency affect quality of digital signal?

If the sampling frequency is too low, aliasing distortion can result. Aliasing is a major concern when using analog-to-digital conversion. Improper sampling of the analog signal will cause high-frequency components of the signal to be aliased with genuine lower-frequency components.
