How do you convert sampling rate to frequency?
The sampling frequency or sampling rate, fs, is the average number of samples obtained in one second, thus fs = 1/T. Its unit is sample per second or hertz e.g. 48 kHz is 48,000 samples per second. Reconstructing a continuous function from samples is done by interpolation algorithms.
Is sample rate equal to frequency?
The sample rate (or sampling rate) is the number of samples taken per second. The units for sample rate are samples per second (sps) or Hertz (Hz). The two are equivalent since the Hertz is equal to the reciprocal second, [Hz]=[s-1].
What is the Nyquist frequency of a 48khz sample rate?
Sample Rate Defined
The Nyquist Theorem states that the highest audio frequency we can record is half of the frequency of the sampling rate. This means that with a sample rate of 44.1 kHz, we can record audio signals up to 22.05 kHz. Likewise, a 96 kHz sample rate allows for 48 kHz of audio bandwidth.
What is the sampling rate of 44.1 kHz?
The sample rate of 44.1 kHz technically allows for audio at frequencies up to 22.05 kHz to be recorded. By placing the Nyquist frequency outside of our hearing range, we can use more moderate filters to eliminate aliasing without much audible effect.
