Indicated on an 80's Radio Electronics, this circuit provides at its output a voltage that is the peak value of the input voltage. The supply voltage must be higher than the expected peak.
We found this circuit in an old American publication. The transistors can be BC558 and diode 1N34....
This simple circuit operates with only 1.5 volts of a battery and detects low resistance making a...
The cascade connection of two flip-flops allows division by 4, as shown in the figure. Note that...
