ABSTRACT:
A variable gain amplifier controlled by alternate sources of gain-control signal. A first, substantially, constant, source has an amplitude corresponding to the amplifier's maximum gain condition. A second, variable, source allows the amplifier gain to be continuously varied. In a chrominance amplifier for a television receiver, the continuously variable source is normally selected so as to develop the desired chrominance level. During the reception of a VIR signal, the constant source is selected so as to effect the maximum amount of VIR correction. The gain-control sources are switched, via analog gates, through substantially identical filter-decoupling networks.
