With this circuit it is possible to select transistors and their compliant test. Or circuit consists of an oscillator. Or transformer of the type found in old transistor radios.
Found in old documentation about neon lamps, this circuit produces very low frequency signals that...
In the figure we show how to use a small Hartley oscillator as a continuity tester. The component...
In the figure we have a interfacing circuit of TTL logic as CMOS logic using a 6N139 optical...
