WebAug 15, 2011 · Sample rate: 44.1 kHz Stop-band: < 12 kHz Stop-band rejection: > 80 dB Pass-band: > 15 kHz Passband ripple: +/- 1 dB You can then feed these parameters into a filter design package and this will give you all the filter coefficients etc. WebWhich, in a few phrases, is explained as follows: Draw a square pulse in the frequency domain that starts from DC (0 Hz) and stops at the cut-off frequency of your low pass filter. Do an inverse DFT of that and this results to a sinc pulse. Use that sinc to filter your data. The longer the sinc, the sharper the cut off.
