WebThe design of optimum equiripple FIR Hilbert transformers is usually performed by Parks-McClellan algorithm. Using the MATLAB Signal Processing Toolbox, this becomes a straightforward procedure through the function firpm. However, for small transition bandwidth and small ripples the resulting filter requires a very high length. This complexity WebThe Hilbert transform facilitates the formation of the analytic signal. The analytic signal is useful in the area of communications, particularly in bandpass signal processing. The toolbox function hilbert computes the Hilbert transform for a real input sequence x and returns a complex result of the same length, y = hilbert (x), where the real ...

The MatLab function hilbert () does actually not compute the Hilbert transform directly but instead it computes the analytical signal, which is the thing one needs in most cases. It does it by taking the FFT, deleting the negative frequencies (setting the upper half of the array to zero) and applying the inverse FFT.

Web[yupper,ylower] = envelope(x) returns the upper and lower envelopes of the input sequence, x, as the magnitude of its analytic signal. The analytic signal of x is found using the discrete Fourier transform as implemented in hilbert.The function initially removes the mean of x and adds it back after computing the envelopes.
