Abstract

PURPOSE:To exactly take the tuning, by aplying the control voltage which has been nonlinear-quantized, to a variable capacitor. CONSTITUTION:In accordance with sennsitivity characteristics of a variable capacitor, the range form higher receiving frequency, for instance, 90MHz and about + or -3V1, to lower receiving frequency, for instance, 76MHz and about + or -1V is separated by 64 steps, and it is applied to the variable capacitor in the form of voltage superposed on the variable capacitor control voltage which has been applied analogously. The voltage is applied in order, and when the peak is detected, its voltage is stored in the memory as optimum voltage of the variable capacitor.
