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.

Signal and tone generators circuit for Testing and adjustments of audio and Measuring instruments particularly important aids and belong to the basic equipment of a Hobby laboratories. 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.
The Web This site. Astables can be constructed around op amps and may use fewer components than the BJT designs described in Oscillators Module 4. Op amp designs are very useful, especially at low frequencies; at higher frequencies however, unless high speed op amps are used a problem occurs, as many standard and older design op amps are not able to handle the very fast voltage transitions required for good square wave shape, due to slew rate limiting. However, a typical slew rate for many popular op amps may be around 0. A number of op amps fit this specification and some may also operate from a single power supply of 3V or less. The operation of the circuit relies on repeatedly charging and discharging C1 from the output of the op amp via R5; these two components therefore set the operating frequency of the oscillator.
By Louis E. The sine wave is a naturally occurring signal shape in communications and other electronic applications. Many electronic products use signals of the sine wave form. Audio, radio, and power equipment usually generates or processes sine waves. As it turns out, there are literally dozens of ways to generate a sine wave. This article presents some popular methods you should be familiar with.
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. In addition to producing sine waves, function generators may typically produce other repetitive waveforms including sawtooth and triangular waveforms, square waves, and pulses. Another feature included on many function generators is the ability to add a DC offset. Although function generators cover both audio and RF frequencies, they are usually not suitable for applications that need low distortion or stable frequency signals.
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.
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.
