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?.

Sampling-Rate Conversion: Non-Integer Sampling-Rate Changes

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. Websampling rate conversion between any rational ratio of sam-pling frequencies can be efficiently implemented by a two-stage process consisting of an integer sampling rate increase followed by an integer sampling rate decrease. Bellanger et a!. [5] found that efficient implementations of low-pass FIR filters could be obtained by a process of ... WebMar 1, 2010 · For inputs sampled at F s, the rate for filtered output data can be reduced to F s /M without loss of information, using a “decimation” process (Figure 2). M can have any integer value, on condition that the output data rate is more than twice the signal bandwidth. Oversampling and averaging increases the SNR, which is equivalent to gaining additional … nothing that our god can\u0027t do

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.
