Abstract
The gain of a wideband tuned transistor amplifier may be varied over a large range by an external control voltage, accompanied by only slight changes in amplifier bandwidth or center frequency, by means of a unique constant-resistance agc attenuator. The control power required by this attenuator is in the milliwatt region. At audio frequencies this relatively simple attenuator may be used to obtain tine arithmetic operations of multiplication and division.
