Function generator

function generator , square, triangle, and sawtooth waveforms In electrical engineering, a function generator is usually a piece of electronic test equipment or software used to generate different types of electrical waveforms over a wide range of frequencies. Some of the most common waveforms produced by the function generator are the sine wave, square wave, triangular wave and sawtooth shapes. These waveforms can be either repetitive or single-shot (which requires an internal or external trigger source). Another feature included on many function generators is the ability to add a DC offset. Integrated circuits used to generate waveforms may also be described as function generator ICs. Although function generators cover both audio and radio frequencies, they are usually not suitable for applications that need low distortion or stable frequency signals. When those traits are required, other signal generators would be more appropriate. Some function generators can be phase-locked to an external signal source (which may be a frequency reference) or another function generator. Function generators are used in the development, test and repair of electronic equipment. For example, they may be used as a signal source to test amplifiers or to introduce an error signal into a control loop.…

Function generators are primarily used for working with analog circuits, related pulse generators are primarily used for working with digital circuits. ===Waveform generator=== An electronic circuit element used for generating waveforms within other apparatus that can be used in communications and instrumentation circuits, and also in a function generator instrument. Examples are the Exar XR2206 and , which can generate sine, square, triangle, ramp, and pulse waveforms at a voltage-controllable frequency. ===Function generator=== An electronic circuit element that provides an output proportional to some mathematical function (such as the square root) of its input; such devices are used in feedback control systems and in analog computers. Examples are the Raytheon QK329 square-law tube and the Intersil ICL8048 Log/Antilog Amplifier.
