Function Generator
What is meant by frequency response and how does Function Generator measure it?
Frequency Response is a tool for measuring how the amplitude and phase of a system’s output signal change with respect to the input frequency signal. Function Generator measures frequency response by generating a sine wave and analyzing it after passing it through device whose frequency response is to be measured.
Is Function Generator AC or DC?
We see that function generator is used for generating periodic waveforms such as sine, square, or triangular waves. These waveforms are continuously changing in direction and magnitude hence Functional generator is AC.
Who invented Function Generator?
Hewlett-Packard Co. had a function generator in 1951. Robert Brunner designed it for testing, vibration and geophysical studies.
Function Generator
In the field of electronics engineering, scientists and researchers often require signals that can be fed as an input to various devices which can later test their devices on these signals. Devices like modulators, filters, and analog-to-digital convertors require some input signals and other signals for testing. You will wonder what researchers do to get these signals. The answer to this is Function Generator. These are the devices that can generate different types of signals each representing different functions. These can be trigonometric signals, square functions, or any other necessary function. In this article we will see what is a function generator, we will also see the block diagram of a function generator and understand its working through it.
