What Is A Function Generator And What Is It Used For? Analysis Of A Function Generator. It is basically piece of test gear for anyone looking to to check and even manufacture electronic gadgets.
Fundamentally it is something that produces a number of kinds of waveforms that are used to test and build many different types of electronic gear. You may additionally see it labeled as a signal generator, since it will make a variety of waveforms or functions.
That previous explanation probably gives a more accurate suggestion of what a function generator actually does. Contingent on what the aim of the device you are developing or testing, will establish what type of function or wave you require to test out fully.
Typical signals which you will observe are Sine Waves, which nearly everybody will recognise, but also frequently used functions or waves, are Saw Tooth, Square Waves and Triangular. I'm sure there are many more but again the equipment you are checking will be the deciding factor as to which of those are necessary. Also the scale and repetition of the waves produced are generally manually set on the function generator, normally by the turning of a button or flicking of a switch.
Whilst most Function Generators are good items of equipment that sit in your work area, it's also possible to get software programs for the computer that will do a similar task. It is a matter of personal preference as to whether you will be a little more comfortable having a gadget that you can lay a hand on, handle and push switches on or whether you might be happy to alter controls and parameters in a computer program. The results are similar though.
If you want to make certain that the right wave form is being created, merely connect to an oscilloscope.
If you are considering a Function Generator, then I'm sure I don't need to describe an oscilloscope. But in the event that I do, what you will get is a visual illustration of the output signal. For those who have ever seen ER or some other hospital performance on TV, that gadget where you can see the heart rate beat, well that's a kind of oscilloscope. And guess what, the heart would be the function generator.
