So, the process to determine the required sample rate is:

How to choose sampling frequency. With a sampling rate of 44,100 hz, the highest frequency you can sample is 22,050 hz. Recording the time when you read the first sample of the frame;. Answers (1) what is your objective:

This is known as the nyquist frequency. Sampling rate = samples per second. This is an engineering decision that will require some thought.

So in your example where you. Learn more about sampling frequency, temporel representations In order to get the most accurate frequency estimate,.

When selecting the sampling rate, the rule of thumb is that it should be 2.56 times greater than the highest frequency that you want to measure; You'd certainly want a sampling interval t safely smaller than 1/2f (the nyquist frequency) as simon bridge mentions. For audio signals we may have frequencies to above 50khz, but only.

The choice of sampling rate is determined from the highest frequency present in significant amount in the signal. Decide what bandwidth you need ( fd ). Since your fft frame will be several samples long, you could think about:

In some cases, tradition may be. The sampling rate you use is directly related to the range of frequencies you can sample. Sample time should be at least 10 times smaller than the time constant, as i decribed in the previous question rule of thumb for choosing a best sampling rate;
