We found these circuits in a 90s Radio Electronics. In them, we have the way to turn a load on and off using pressure switches. The circuit can be used with other types of direct current load.
The presented circuit makes use of two hybrid modules (see articles on the website) to drive a...
With this simple tester you can measure the gain of an NPN or PNP transistor. The instrument can...
This circuit amplifies signals only in the frequency range determined by the double T. The circuit is...
