How do you filter a signal in Python?

Well for starters, to filter a signal, we can simply take the impulse response of that filter and convolve it with the signal. FIR filtering is simply a convolution operation. It might be confusing because earlier we mentioned that convolution takes in two signals and outputs one.

How to filter ECG in Python?

read('ecg. wav') times = np. arange(len(data))/sampleRate # apply a 3-pole lowpass filter at 0.1x Nyquist frequency b, a = scipy. signal.
