  • Abstract
    The paper examines the use of the multiplying digital-to-analogue convertor (DAC) in op-amp inverting summers and integrators. The digitally controlled analogue filtering circuits are obtained when analogue computer-type RC filters are implemented with digitally controlled summers and integrators. An example of a fully programmable state variable bandpass filter is outlined.
