Abstract: PURPOSE: To prevent creep, by opening or closing a gate provided between a counter and an integrator, which integrates the output of a power detector depending on the result of comparison of the output signal of a load current detector with a reference signal, to control the operation of the counter.  
     CONSTITUTION: The product of the outputs eV, eI of a voltage detector 51 and a current detector 52 is determined by a power detector 54, the output of which is changed into a pulse frequency by an integrator 55 such as a current-frequency converter. The output pulses of the integrator 55 are passed through a gate means 56 and counted by a counter 57 to detect the quantity of electric power. The output eI of the current detector 52 is compared with a reference voltage 59 by a comparator 57. When the output eI is higher than the reference voltage 59, the output pulses of the integrator 55 are supplied to the counter 57 to determine the quantity of electric power. When the output eI is not higher than the reference voltage 59, the gate means 56 is closed not to supply the output pulses of the integrator 55 to the counter 57. As a result, the output pulses of the integrator 55 are not supplied to the counter 57 even if there is a creep output.

Abstract: PURPOSE: To make channel selection frequency display of multiple bands possible by comparing a stair case wave, which is changed according to the counted value of clock pulses, with a voltage, which is set by a tuning volume, to detect agreement of them in the tuning unit which displays channel selection frequencies.  
     CONSTITUTION: Clock pulses from a reference oscillator become stair case wave voltage G 2 , which is changed according to the counted value of clock pulses, through counter circuit 6 and D/A converter 7. This voltage is compared with voltage G 1  set by manual tuning volume VR 1 . In case of agreement between voltages G 1  and G 2 , counter 6 stops counting operations, and the output of counter 6 is displayed digitally on display unit 11 through decoder 10. Consequently, UHF and VHF bands can be displayed because the output frequency of the local oscillator of the tuner is not used.
