1,193,504. A.G.C. circuits. MATSUSHITA ELECTRONICS CORP. 24 March, 1967 [24 March, 1966], No. 11892/67. Heading H3T. An A.G.C. circuit comprises a two gate, insulated gate field effect transistor with means to apply a fixed voltage to one gate electrode (4) and a second (input signal) voltage to a second gate electrode (3) which is arranged to operate near the current saturation point, and the A.G.C. signal, derived for example from the output circuit by means of rectifier 6, is applied to the first or second gate electrode.
