I am trying to get some knowledge about FIR filters. According to above link FIR filter is just the convolution of a sampled input signal to impulse response of a filter. I have done some research and according to some texts FIR is the same as calculating the moving average of the input samples and there is no talk about impulse response. It seems if we take the moving average we can create a filter.
I would appreciate it if someone could help me to understand FIR filter . According to tutorials here we make FIR filter by just delaying the samples .https://greatscottgadgets.com/sdr/10/
