understanding signal generator

Signal generator is used to check if there is any problem in your electronic appliances. This generator will only be used on the appliances that receive or produce signal, such as radio, and television. This device will check the transmission of the signal. If you have your radio transmission is disturbed or not good, this device will help you to find the problem.

This device is usually used in transmitter or station. They will be checked regularly to control the signal quality so that the radio station or television station will broadcast successfully.

As it is stated on the paragraph above, you will need ac signal generator with a certain frequency of certain amplitude to the input system. You can examine the results that produced in other parts of the system. Electronic things that produce such signals are known as signal generator.

Simple signal generator can produce sine-wave or square wave and ac voltage at certain frequency from 20 to more than 20.000HZ, the output voltage will be various from 10 Vrms drops to zero. Oscillator feedback 360 degrees with Wien-2 component is the common series for this generator. It would provide AC current sine-wave. An amplifier will increase the output.

Sine-wave AC voltage needs to be strengthen if you want to get AC voltage square wave. You should cut the amplitude with a parallel diode. AF signal generator can be used with a series of electronic square wave formation, such as Schmitt trigger circuit to produce a square wave output.

Function generator produces various waves such as sine-wave, square-wave, etc. they are produced in different size, shape and climb voltage or sweeping. Function generator works in low frequency less than 1 Hz till more than 10Mhz. this generator can be a LC oscillator or synthesizer system.

Most of this signal generator is produced to work at 50 or 600. The out put can be adjusted around 10V to 0V.
