I would like to apply a filter bank decomposition over a time series signal. If I am correct, it is necessary to take a low pass and a high pass filter, and then convolve them with the time series.

Can you provide the easiest example where on which I can apply this decomposition where I can attempt the calculation numerically?

Thanks in advance.
