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.

Why does increasing the sample size lower the (sampling) variance?

"Webincrease and reduce the sampling rate or frequency, usually by an integer factor. Increasing of a sampling rate requires that new values, not presented in the signal, be computed and inserted between the existing samples. The new value is estimated from a neighborhood of the samples of the original signal. " - Increase sample rate by integer factor

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.
