Description

Uses a hilbert transformer filter to get 90 degrees phase shifted version of the original and then forms the envelope like this:


       envelope[i] = sqrt(sqr(X[i-HilbertDelay]) + sqr(Y[i]));

This is an alternative way to detect the envelope in comparison to the method offered by TSignalDecimator. This approach is slower, but could result in significant noise reduction.
