Averaging filters
If a signal undergoes repeated averaging (n times) with a filter (h) of size m. Is it possible to achieve the same averaging result with an averaging filter(H) of a larger size?
h = {1/m, 1/m... m times}

What are the ripple and attenuation in a set of moving average filters?
Ladies, Gentlemen,
Consider following set of moving average filters:
(1) - 100 coefficients equal to 1/100
(2) --- 95 coefficients equal to 1/95
(3) --- 90 coefficients equal to 1/90
(4) --- 85 coefficients equal to 1/85
(5) --- 80 coefficients…

How is that after random numbers with their negatives alternating passing through 5, 4, 3 order moving average filter, become quasi sinusoidals?
I have passed random numbers $${89, 58, 13, 70, 24}$$ with their negatives alternating, through 5 order moving average filter and output was positive and negative numbers alternating. After I have passed output through 4 order mov. average filter,…

Boxcar, Removing DC signal from an ADC on a FPGA
I have been reading on different ways to do this.
I have seen this Linear-phase DC Removal Filter
This seems like it would work just fine, but it would take some time to implement.
Is there any reason you can't just say average 16192 * 256 samples…
