How to calculate the sampling rate?
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.
How do you choose a sampling rate based on frequency?
The Nyquist theorem – choosing the right sample rate
The Nyquist theorem is part of the fundamentals of signal conditioning. Based on that, you must choose the sample rate at least twice as high as the maximum frequency in the signal.
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].
How do you find minimum sampling rate from frequency?
MINIMUM NUMBER OF SAMPLES
f. The sampling theorem states that a real signal, f(t), which is band-limited to f Hz can be reconstructed without error from samples taken uniformly at a rate R > 2f samples per second. This minimum sampling frequency, fs = 2f Hz, is called the Nyquist rate or the Nyquist frequency (6).
