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 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...
