How to design very narrow band, very sharp low pass filters - Only DC needed?
I am using a DSP processor to sample signals at 108kHz and I only want to get the DC part out of it. Such a high sampling rate is used because I want to use oversampling to reduce quantization noises. …

How to design very narrow, sharp lowpass filters - Only DC needed?
I asked exact the same here one year ago: One year ago question I asked this question again here, because after one year, I have learned more about DSP and am thinking ways to improve it.
Filter desc …

Comparing with FIR, why does IIR always gives a bias error, when calculating signal DC?
I am trying the DC blocking function in matlab. The algorithm of DC blocking is to find DC of the signal first and then remove the DC value from the signals. Here are the codes I tried, which are samp …
