What is the principle of a signal generator?

[AutumnLynn]

The principle of a signal generator is to generate a low-frequency sinusoidal oscillation signal through the main oscillator stage, which is then amplified by a voltage amplifier to meet the voltage output amplitude requirements. The output can be directly obtained through an output attenuator, and the output voltage can be adjusted using the main oscillator output potentiometer. Signal generators, also known as signal sources or oscillators, are used to generate specific electrical test signals required by the circuit under test. They have wide applications in production practices and scientific technologies. Various waveforms can be represented by trigonometric function equations, and circuits that can generate different waveforms, such as triangular waves, sawtooth waves, rectangular waves, and sine waves, are also known as function signal generators.
