The original purpose of this circuit, which we find in old American documentation, is to modulate an RF carrier for telecommunications applications. Transistors support equivalents.
In this circuit we show how to configure the LM3914 as a bargraph or moving point, supplying 10...
We found this circuit in a documentation for 1977 American radio amateurs. The LM336 integrated circuit...
This modulator circuit is nothing more than an audio amplifier that serves to modulate amplitude...
