OSCILLATION FREQUENCY CONTROL CIRCUIT

摘要

PURPOSE:To obtain the oscillation control circuit which is composed of a simple circuit while adjustment man-hours are decreased, and suitably mass-produced at low cost. CONSTITUTION:The oscillation frequency control circuit is equipped with an amplifying circuit with a gain controller equipped with an F-V converting circuit S1 which generates a voltage corresponding to an input frequency, a variable resistor R1 for its gain control, and an oscillation circuit wherein the output of the F-V converting circuit is connected to an oscillator through a voltage- current converter.
