received at physically diverse locations and which have been converted from radio frequency to intermediate frequency each of the signals is checked for signal strength and for amplitude versus frequency dispersion each signal is run through a separate amplitude slope equalizer which removes amplitude slope each signal is then run through a separate squelch circuit which either attenuates the signal or passes it on undiminished the squelch circuits are controlled by a control circuit which selectively activates one or neither of the squelch circuits based on the difference in signal strength between the two received signals and the signal dispersion of each of the signals the outputs of the squelching circuits are then combined to create a composite signal which is comprised of one or both of the equalized signals application_number US 10041393 A description fig1 depicts a radio receiving system with a frequency down converter andan intermediate frequency combiner in such a system two antennas are located at physically diverse locations each of which is intended to receive the same signal the purpose of the separation is to overcome multipath fading effects in fig1 the two antennas 2 and 4 receive a signal and send it to frequency down converters 10 and 12 for the purposes of this description the signal received by antenna 2 is to be called signal a and the signal received by antenna 4 is to be called signal b the single oscillator 6 provides a signal to a signal splitter 8 which splits the signal and provides it to the two frequency down converters 10 and 12 the frequency down converter for signal.
