What is signal generator?

A signal generator is an electronic device that produces repeating or non-repeating electronic signals (either analog or digital). It is commonly used to generate signals for testing, designing, troubleshooting, and repairing electronic devices. Signal generators can produce a wide variety of waveforms, such as sine waves, square waves, triangle waves, and pulses, and can also modulate these waveforms in various ways. They are widely used in telecommunications, audio engineering, and other fields requiring precise signal control.
