This circuit switches on an external load after a certain interval given by the capacitor. The circuit is from a documentation from the 80s. The load depends on the relay used.
We present a circuit formed by six voltage comparators. Each comparator will analyze the voltage...
This circuit can generate time base signals from 5 to 1500 Hz. We find it in a documentation about old neon...
In this circuit the CA3140, an operational amplifier, is used as a comparator with the zener diode...
