Abstract : An automatic gain control system is disclosed which utilizes a voltage controlled vario-losser means to vary the AGC system output. The control voltage is derived from the lowest detected level from any of a plurality of narrow band pass filters, such as the monolithic crystal type now available, each of which has a different peak transmittance frequency which is close to but different from a frequency of interest.
