What happens when the sampling frequency 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.
What is the relation between sampling frequency and signal frequency?
The sampling rate must be equal or superior to the double of the highest frequency or the signal .
What is the sampling frequency of an audio signal?
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.
What happens when your sampling rate is higher than twice the maximum frequency of your signal?
The science behind sample rates goes back to the 1940s, with the development of the Nyquist–Shannon theorem. The theorem states that when the sampling frequency is greater than twice the maximum frequency of the signal being sampled, the original signal can be faithfully reconstructed.
