  • Patent number: 3976894
    Abstract: An analog divider network is disclosed wherein an operational amplifier includes a feedback impedance coupled between an input terminal and output terminal of such amplifier through a switching network. The input terminal of such amplifier is coupled to the "numerator" analog signal applied to the analog divider network. Means are provided for actuating the switching network to periodically decouple the feedback impedance from the input and output terminals for a time duration inversely proportional to the magnitude of the "denominator" analog signal, thereby to provide an output signal proportional to the ratio of the "numerator" analog signal to the "denominator" signal.
