What is Signal Generator? �Is electronic device that generate repeating or nonrepeating electronic signals �They are generally used in designing, testing, troubleshooting, and repairing electronic devices

�There are many different types of signal generators, with different purposes and applications I. Function generators II. Analog signal generators III. Vector signal generators

Function Generator �Definition: Is usually a piece of electronic test equipment or software used to generate different types of electrical Waveform over a wide range of frequencies. � Some of the most common waveforms produced by the function generator are: The sine, square, triangular and sawtooth shapes.

Function generator controls �Frequency: this control alters the basic frequency at which the waveform repeats. �Waveform type: sine, Square or Triangular wave. �DC offset: This alters the average voltage of a signal relative to 0 V or ground. �Duty cycle: This control on the function generator changes the ratio of high voltage to low voltage time in a square wave signal

Usages Of Function Generator: Function generators are used in the development, test and repair of electronic equipment. Example: They may be used as a signal source to test amplifiers or to introduce an error signal into a control loop

Function Generator Specifications: �Produces sine, square, triangular, sawtooth (ramp), and pulse output. �It can generate a wide range of frequencies. �AM or FM modulation may be supported. �Output amplitude up to 10 V peak to peak. �An output impedance of 50 ohms. Note: These are some of the specifications there are other specifications due to the number of different types available ranging from analogue to digital, and according to their cost.

How To Build a Function Generator • Circuit in general • Sin wave • Triangle wave • Square wave
