This high-precision circuit was found in documentation from the 1990s. The integrated circuit is an LM111 or another in the series. The circuit has TTL output and can function as a shield.
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...
