ABSTRACT:
A broadband amplifier with a negative feedback circuit having a variable resistance means and first and second parallel resistor-inductor combinations for slope control is shown. The variable resistance means establishes the overall frequency response and can be electronically varied to provide automatic gain control. The first and second parallel resistor-inductor combinations provide compensation for deviations from the desired frequency response over respective first and second frequency ranges.
