ABSTRACT:
An electronic tuning type receiver comprises a digital-to-analog conversion section having a memory adapted to store a digital input value obtained by counting pulses generated by a manual operation. In one embodiment an up-down counter is also employed. A digital-to-analog conversion process section generates a pulse signal having a number of pulses per unit time corresponding to an output of the memory or counter and a tuning section receives as a tuning signal, an analog output signal of the digital-to-analog conversion section. The receiver further comprises an electric source "off" state detecting circuit which, in one embodiment only when both of the outputs of the digital-to-analog conversion process section and an electric source thereof are brought to be in "off" state, operates to suspend the operations of relevant sections of the receiver. In another embodiment the up-down counter and pulse oscillator are suspended when the power is switched off.
