Abstract
An electronic transmit/receive device employs an equalized envelope derived timing system to compensate for differential time delay occurring at upper and lower bandedges of the received signal. The received signal is split into a complex signal and the envelope derived timing system is utilized to perform amplitude and delay distortion compensation on the received signal. The amplitude and delay distortion compensation is performed by employing bandedge filters which preferably take the form of Finite Impulse Response (FIR) filters.
