Sample Rate Nyquist Theorem
Nyquist bit rate theorem nyquist theorem for sampling what is the nyquist sampling theorem nyquist sampling theorem definition sampling rate and nyquist rate define nyquist sampling theorem sample rate nyquist nyquist frequency from sample rate nyquist sample rate formula sample rate audio sample rate vs bit rate sample rate windows
Sample Rate Nyquist Theorem. If we were to store sound, like music, to a cd, the audio signal must be . In order to have the signal be uniquely reconstructed without aliasing.
In order to have the signal be uniquely reconstructed without aliasing.
The sampling frequency should be at least twice the highest frequency contained in the signal. According to the nyquist theorem, the sampling rate must be at least . The frequency 2·fmax is called the nyquist sampling rate. As an example, humans can detect or hear frequenies in the range of 20 hz to 20,000 hz.
