Title: Nonlinear side band emphasis circuit
Inventor: IKEDA KAZUMASA
IPC: H03G9/02
Filed: 1982-12-23
Abstract: PURPOSE:To apply nonlinear emphasis to a side band component by inserting a nonlinear element to a negative feedback path of a differential input form and connecting a parallel resonance circuit between an inverting input terminal and a ground. CONSTITUTION:Diodes 2, 3 of antiparallel connection are used for the nonlinear element of a negative feedback system. Then, when the level of an input signal S is small, the output level is also small, the diodes 2, 3 go to a high-impedance state and no negative feedback gives effect on the gain. When the level of the input signal S is large, the output level is also large, the diodes 2, 3 to go a low- impedance state, resulting in that the negative feedback amount is increased and the gain is suppressed. This fact gives effects on the emphasis characteristic of the system depending on the parallel resonance circuit 7 and a series resistor 8, and the overall emphasis characteristic becomes the nonlinear side band emphasis characteristic with respect to the input signal level.
