Modify a FIR filter in the frequency domain a then accomplish IFFT
Started by 2 years ago●8 replies●latest reply 2 years ago●303 viewsHallo,I would like to design a custom made FIR filter. I would start from an ordinary LP FIR filter designed by means of fdatool, for instance, and then modify the...
bandpass filter from summed lightly-damped transfer functions
Started by 2 years ago●2 replies●latest reply 2 years ago●278 viewsI would like to make a bandpass filter for an SDR project by passing the signal through two (or more) transfer functions in parallel. Each transfer function uses...
Hi All,It is common knowledge that FFT followed by iFFT is an alternative for time domain convolution. However, I read many articles explaining this method on the...
