A function generator is a piece of electronic test equipment used to generate electrical waveforms. These waveforms can be either repetitive, or single-shot (once only) in which case some kind of triggering source is required (internal or external). The resultant waveforms can be injected into a device under test and analyzed as they progress through the device, confirming the proper operation of the device or pinpointing a fault in it. Wikipedia does not have an article with this exact name. ...

In trigonometry, an ideal sine wave is a waveform whose graph is identical to the generalized sine function y = Asin[ω(x − α)] + C, where A is the amplitude, ω is the angular frequency (2π/P where P is the wavelength), α is the phase shift, and C is the...

Function generators usually generate a triangle waveform as their basic output. The triangle is generated by repeatedly charging and discharging a capacitor from a constant current source. This produces a linearly ascending or descending voltage ramp. As the output voltage reaches upper and lower limits, the charging and discharging is reversed, producing the linear triangle wave. By varying the current and the size of the capacitor, different frequencies may be obtained. A triangle wave is a waveform named for its triangular shape. ...

A 50% duty cycle square wave is easily obtained by noting whether the capacitor is being charged or discharged. Most function generators also contain a diode shaping circuit that can convert the triangle wave into a reasonably accurate sine wave. In telecommunication, the term duty cycle has the following meanings: In an ideal pulse train, that is, one having rectangular pulses, the ratio of the pulse duration to the pulse period. ...

The type of output connector from the device depends on the frequency range of the generator. A typical function generator can provide frequencies up to 20 MHz and uses a BNC connector, usually requiring a 50 or 75 ohm termination. Specialised RF generators are capable of gigahertz frequencies and typically use N-type output connectors.

Function generators, like most signal generators, may also contain an attenuator, various means of modulating the output waveform, and often the ability to automatically and repetitively "sweep" the frequency of the output waveform (by means of a voltage-controlled oscillator) between two operator-determined limits. This capability makes it very easy to evaluate the frequency response of a given electronic circuit. It has been suggested that this article or section be merged with Function generator. ...
