ABSTRACT:
A logarithmic compression circuit comprising an operational amplifier and a transistor for logarithmic compression. One of the emitter and collector of the transistor is connected to the inverting input of the amplifier and the other of the emitter and collector of the transistor is connected to the output of the amplifier. A switching device is selectively connected between the base of the transistor and the non-inverting input of the amplifier and between the base and the said one of the emitter and collector of the transistor in accordance with the magnitude of a signal current input.
