Increase sample rate by integer factor
WebMar 29, 2015 · 2. You are seeing several things when you increase the sample rate: most (forward) FFT implementations have an implicit scaling factor of N (sometimes sqrt (N)) - if you're increasing your FFT size as you increase the sample rate (i.e. keeping the time window constant) then the apparent magnitude of the peaks in the FFT will increase. http://www.ece.northwestern.edu/local-apps/matlabhelp/toolbox/signal/interp.html#:~:text=Increase%20sampling%20rate%20by%20an%20integer%20factor%20%28interpolation%29,%3D%20interp%20%28x%2Cr%2Cl%2Calpha%29%20%5By%2Cb%5D%20%3D%20interp%20%28x%2Cr%2Cl%2Calpha%29%20Description

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. WebUse a moderate upsampling factor of 3 to avoid overfitting. fs = 1; [y,ty] = resample(yg,t,fs,3,1); ... Now increase the sample rate to two measurements per day and use spline interpolation. Plot the result. ... The sample rate is …
Web1.1 Upsampling: An Upsampler with sampling factor L, where L is a positive integer and every Lth sample is takenfrom x[n] with all others zero which develops an output sequence x e [n] with a sampling rate that is L times greater than that of the input sequence. Fig. 1 Block-diagram representation 1.2 Downsampling:A down-sampler with a down ... 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 …
