Signal Generators

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.

Function Generator

A function generator is a signal source that has the capability of producing different types of waveforms as its output signal. The most common output waveforms are sine-waves, triangular waves , square waves , and sawtooth waves. The frequencies of such waveforms may be adjusted from a fraction of a hertz to several hundred kHz. Actually, the function generators are very versatile instruments as they are capable of producing a wide variety of waveforms and frequencies. In fact, each of the waveforms they generate is particularly suitable for a different group of applications. The uses of sinusoidal outputs and square-wave outputs have already been described in the earlier Arts. The triangular-wave and sawtooth wave outputs of function generators are commonly used for those applications which need a signal that increases or reduces at a specific linear rate.

Signal generator is an electronic equipment that provides standard test signals like sine wave, square wave, triangular wave and etc. It is also called an oscillator, since it produces periodic signals. The signal generator, which produces the periodic signal having a frequency of Audio Frequency AF range is called AF signal generator. The AF signal generator, which generates either sine wave or square wave in the range of audio frequencies based on the requirement is called AF Sine and Square wave generator. Its block diagram is shown in below figure. The above block diagram consists of mainly two paths. Those are upper path and lower path.

Six wave-selector buttons. The six waveforms that the function generator can produce are the sine wave, the square wave, the triangl e wave, two saw tooth waves, and the variable-w idth pulse wave. Figure 2 : A v a ilable Ge ne ra te d Wa v e forms. The post explains a very simple 3-phase sine wave generator circuit, using only three bipolar transistors and a few passive components for initiating the desired three phase output. How it Works Referring to the 3 phase sine wave generator circuit we can see three identical transistor stages configured in a cross coupled manner, having. Sine wave generator using diode network Forum for Electronics.

Unlike RF generators and some others that only create sine waves, the function generator is able to create repetitive waveforms with a number of common shapes. In particular it can be made to become a sine wave generator, square wave generator, and triangular wave generator. Also a function generator may be able to vary the characteristics of the waveforms, changing the length of the pulse, i. It cannot be programmed to create additional waveforms - an arbitrary waveform generator, AWG is required for this. Apart from just generating the waveforms themselves, this type of test instrument has the capability to add a DC offset to the signal. This can be very useful in a number of testing applications.

With respect to the waveform are often high demands on provided a sine generator, with the simple function generators not must be met. The frequency of the generator is in switchable four decades and within the Decades infinitely adjustable with a potentiometer. Furthermore, the output level of the SG is variable up to max. For power supply can be optionally an unstabilized 2V power supply or a 9V battery used.
