Here are some analog Hilbert Transformer references to get you started. They work by using two all-pass filter sections where the phase difference betweeen the sections is 90 degrees of the frequency band of interest ----------------------------------------------------------------------------- [1] Frederrick Shirley, "Shift Phase Independent of Frequency," Electronic Design 18, Sept, 1970, pp. 62-66.
