This circuit visually indicates that a high voltage is present in an outlet or other point. The neon lamp is common, and the appearance of the assembly is suggested in the same figure.
In the figure we show how to implement a voltage reference with the ON Semiconductor rail-to-rail...
This circuit is from a technical documentation from 1978. The maximum output current is of the...
This RF and audio follower applies its signals to a small amplifier. The FET can be any...
