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 … WebFor instance, to implement a 24-bit converter, it is sufficient to use a 20-bit converter that can run at 256 times the target sampling rate. Combining 256 consecutive 20-bit samples can increase the SNR by a factor of 16, effectively adding 4 bits to the resolution and producing a single sample with 24-bit resolution.

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?.
