This circuit uses a 7-segment display to indicate the logic level of a test circuit. The power supply is made with 5 V that can come from the analyzed circuit itself.
The frequency of this oscillator is determined only by the crystal, without the use of tuned...
We found this interesting transistor generator in European documentation from the 1980s. The...
This filter rejects signals below 300 Hz and signals above 3000 Hz, being used in...
