Plot the result. ... The sample rate is … WebRate increase by an integer factor L can be explained as a 2-step process, with an equivalent implementation that is more efficient:. Expansion: Create a sequence, [], comprising the original samples, [], separated by L − 1 zeros. A notation for this operation is: [] = []. Interpolation: Smooth out the discontinuities with a lowpass filter, which replaces the zeros.

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. WebInterpolation increases the original sample rate of a sequence to a higher rate. It is the opposite of decimation. interp inserts zeros into the original signal and then applies a lowpass interpolating filter to the expanded sequence. The function uses the lowpass … Compare the interpolation results produced by spline, pchip, and makima for two …

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).
