で使用する電力消費は大きなものとなる。In a radio receiver with such a configuration, when the number of LED lo is 6, in order to light up from the lower LICD according to the reception level, the number of LKI corresponding to the level is
), there is no need to pass the current to light the light, so especially in equipment that uses batteries, I, KDl 0
The power consumption will be large.

1 & ~11 (1) is the LED corresponding to 10 in Figure 1
, 12 are terminals to which the reception level voltage is applied from the intermediate frequency amplifying section 6, 13 to 19 are terminals, 20 to 32 are resistors, and 33 to 36 are diodes.

ることになる。In this configuration, the circuit except for the diodes 33 to 36 and the comparator 17P-19 is the same as a normal circuit, and the circuit is the same as the normal one, and the circuit is the same as the normal one.
, 31.30, 29.28 respectively comparator 16
, 15, 14, and 13, several dozen LEDs 11 corresponding to the reception level voltage are lit.
ところがダイオード３３Ｐ−３６、およびコンパレーク

灯するようにしている。However, by adding the diodes 33P-36 and comparators 17 to 19, no matter how much power is received or the bell voltage, only one LED corresponding to the voltage is lit.

さ々い。Now, the lighting level of LEDll (11a P-11d) is set by comparator 13A-16. If the set level l of 16 to the comparator 13 is v1/-v4, then if the received voltage is vl<v2, the comparator 13 is set to vl
It compares with the reference voltage and turns on, lighting up LEDlla. At this time, the comparator 17 compares v2 with the received level voltage, and its output is at a low level, but the diode 33 and the comparator 13 are significantly affected.

ａ〜１１０は消える。When the reception level voltage is between v2 and v3, the comparator 14 sets the LICD1 l to the reference level of v2.
Turn on b. At that time, comparator 1a also has v2
Since the input voltage v3 is applied, the output of the comparator 17 becomes high level, and the output of the comparator 13 is inverted through the diode 33. Therefore, LICD
When l l b lights up, LED-11 goes out. If LICDl 1 d lights up, comparator 17

特に電池を使用する機器においては有用である。As is clear from the above embodiments, only one LED corresponding to the peak voltage of the input voltage is turned on for the input voltage according to the reception level or audio level, so the power consumption used by the LED is can be made smaller,
This is particularly useful for devices that use batteries.
