WebOct 24, 2015 · Hilbert Transformers are non-causal, i.e. they need to be delayed to be implementable. So you get the 90 degree phase-shift plus a bulk delay of 20 samples (half the filter length). You see the 90 degree phase shift if you delay the original signal by 20 samples as well. EDIT for Part 2: Your lower bandpass cutoff is too high.

The Fractional Hilbert Transform on the Real Line - Hindawi

WebDigital Hilbert transformers are a special class of digital filter whose characteristic is to introduce a π/2 radians phase shift of the input signal. In the ideal Hilbert transformer all the positive frequency components are shifted by –π/2 radians and all the negative frequency components are shifted by π/2 radians.
