  • Patent number: 4224605
    Abstract: An analog-digital coder applicable for the coding of analog information in accordance with non-linear functions of compression such as the laws A and .mu. as set forth in the standards of the CCITT (International Telegraph and Telephone Consultative Committee). For non-linear coding the analog information is applied to an analog switch whose output signals are applied to an adder which also receives the output voltage of an amplifier. The output voltage of the adder is applied to a multiplier-analog memory which comprises a charge transfer device. Their output is coupled to the input of the amplifier. A comparator compares the output voltage of the multiplier-memory with a given voltage and controls a logic switching circuit which generates the coded output signal.
