ABSTRACT:
A receiver for electric oscillations modulated in SSMA technique with which, in an intermediate frequency position, a multiplier is provided for multiplying the intermediate frequency signal with a code which is to be received, and with which a synchronous demodulator for obtaining the information to be received is connected to the multiplier, wherein the receiver includes in a section preceding the multiplier a gain control amplifier having two control voltage derivation circuits assigned thereto for deriving control signals, one of the voltage derivation circuits operable to evaluate the output signal of the multiplier and other of the voltage derivation circuits operable to evaluate the output of a synchronous demodulator so that in an unsynchronized state of the synchronous demodulator the control signal which is derived from the multiplier output serves to control the gain control amplifier and in the case of synchronous operation the control signal derived from the synchronous demodulator is employed to control the gain control amplifier.
