Abstract

PURPOSE:To simplify the operation by setting a tuning voltage starting to activate a meter and another tuning voltage which activates the meter to a maximum value every band. CONSTITUTION:Data are fetched from a memory 10 by a control circuit 9 every band, and data of voltage starting to activate a meter 7 is given to a D-A converter 5, and the data of voltage which activates the meter 7 to a maximum is given to a digital variable resistor 8. Thus, a voltage from a tuning voltage generator 11 passes through a differential amplifier 6 to be a prescribed characteristic to activate the meter 7. In figure, 12 indicates an electronic tuner.
