Signalgenerator

As a signal generator or electronics modules are denoted producing voltages with a characteristic time.

Variants

Simple signal generators for the low frequency range (LF, audio range and sound ) are commonly referred to as tone generator.

Function generators is called in general such signal generators that generate different simple periodic signals. Most are the sine, square and triangle waves. The respective generators are called according to sine, square and triangle generators. Better device can also generate spikes, rising and falling edges ( triangular and sawtooth waves ) from composite signals as tonal signals as well as various noise signals, for example, White or 1/f-noise.

Signal generator for high-frequency sinusoidal oscillations are also referred to as a measurement channel. These often have a sweep for repeated passage through a frequency range, or have the possibility of frequency and amplitude modulation.

So-called Arbitrary have an edit option for generating arbitrary waveforms. They contain a digital oscillator and work with high-speed digital - to-analog converters, which output the data stored as pulse shape.

Computer as a signal generator

A computer with appropriate software to the signal generator can be by the sound card is used with its digital -to-analog converters for signal output in the simplest case.
