This circuit, which can use the 4011 or 4001, was found in documentation from the 90s. The load depends on the transistor used, and the power supply must be isolated.
The sensors in this circuit are NTCs and PTCs that work in a differential way by directly...
We found this circuit in a 90's Radio Electronics. The circuit can still be easily assembled as all...
Found in a 90s Electronic Design, this circuit rectifies sinusoidal signals providing output as...
