Increase sample rate by integer factor

WebDescription. y = upsample (x,n) increases the sample rate of x by inserting n – 1 zeros between samples. If x is a matrix, the function treats each column as a separate … WebSo here is my understanding, Input Sampling rate = 511 b/s and Desired output sampling rate = 127 b/s. So, 127*5 = 635 and 635 -511 = 124. Therefore, i need to up sample 511 b/s by a factor of L = 5 to get 635 and then down sample this 635 by a factor M = 124 to get the desired down sampled output of 127 b/s. What do you have to say?.

Weby = interp (x,r) increases the sample rate of x, the input signal, by a factor of r. y = interp (x,r,n,cutoff) specifies two additional values: n is half the number of original sample values used to interpolate the expanded signal. cutoff is the normalized cutoff frequency of the input signal, specified as a fraction of the Nyquist frequency. Weby = decimate (x,r) reduces the sample rate of input signal x by a factor of r. The decimated signal y is shortened by a factor of r so that length (y) = ceil (length (x)/r). By default, decimate uses a lowpass Chebyshev Type I …
