How do I set sampling rate in Matlab?

The sampling frequency or sampling rate, fs, is the average number of samples obtained in one second (samples per second), thus fs = 1/T. To sample a signal in MATLAB, generate a time vector at the appropiate rate, and use this to generate the signal.

What is the sampling rate per second?

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 downsample a vector in Matlab?

y = downsample( x , n ) decreases the sample rate of x by keeping the first sample and then every n th sample after the first. If x is a matrix, the function treats each column as a separate sequence. y = downsample( x , n , phase ) specifies the number of samples by which to offset the downsampled sequence.
