I am experimenting with low voltage transistor circuits. Some experiments call for adding a low voltage AC signal into the circuit. Where should this AC signal come from, power supply, signal generator or ??.
Do signal generators allow you to dial up both frequency and amplitude, for example 6V & 2K HZ? I am trying to figure out if I need to build another PS or get a signal generator? In the end I want to build a low power shortwave transmitter.
Sorry for a basic question but can't seem to find an answer on the web.
Thanks!
