Abstract : The receiver comprises a 90 deg hybrid and analog-to-digital converters between the RF section and digital processing; which makes it possible to eliminate a phase correlator, four diode detectors and two differential amplifiers used in previous IFM receivers to obtain the sine and cosine signal samples at an initial time and a delayed time.
