A signal generator provides a high-fidelity sine wave signal ranging from low frequencies to many GHz. Attenuation, modulation, and sweeping are typical features of a signal generator.

A function generator is a lower-frequency instrument that typically provides sine, square, pulse, triangle and ramp waveforms. Function generators provide these standard functions from DC to a few MHz, and provide large voltage ranges.

What is the difference between audio generator and signal generator?

Audio generator will produce some range of frequency and level of a test signal meant for audio. A signal generator will produce a test signal but is a more general classification. For example a audio generator is a signal generator. When you know what type of signal you are looking for, then a signal generator will be called that type of signal. all depends on what you are testing. examples: video -> video signal generator audio -> audio signal generator


What is the difference between a floating output signal generator and a grounded output signal generator?

A signal generator can be used to function in two ways. In high frequencies, one of output probes of any generator (negative probe) will be grounded automatically, hence it has to be connected with grounded parts of other elements not to create a short circuit problem. But, in the case of floating type (f<100 Hz, generally) probes of the signal generator is not grounded.


What is the difference between multichannel and multidimensional signals?

if a signal is a function of single independent variable,then signal is called multichannel signal. if a signal is function of multiple independent variable then signal is called multidimensional signal.


What is the difference between a signal generator and a function generator in electronics?

Signal generator is an electronic device that generates repeating electronic signals (in either the analog or digital domains). They are generally used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devicesA function generator is a device which produces simple repetitive waveforms. Such devices contain an electronic oscillator, a circuit that is capable of creating a repetitive waveformA signal generator is generally understood to be a generator of r.f. (sinewave) signals of known amplitude and accurate and stable frequency. The output signal may be c.w., a.m. or f.m. It may be used to test and align radio receivers.A lower frequency variety would normally be called an a.f. generator.A function generator can produce variety of waveforms, not just sine. Ramp, triangle and square, for example.


What is Difference between dual trace oscillosope and dual trace generator?

Oscilloscope is used to display electrical signals on a display. A dual trace oscilloscope can display two signals simultaneously. For a trace generator I think you mean a signal or a function generator which generates electrical waveforms of varying shapes, frequency and amplitude. A dual trace or a function generator in that sense is an equipment capable of generating two independent waveforms at the same time. - Neeraj


Working of function generator?

After powering on the function generator, the output signal needs to be configured to the desired shape. Typically, this means connecting the signal and ground leads to an oscilloscope to check the controls. Adjust the function generator until the output signal is correct, then attach the signal and ground leads from the function generator to the input and ground of the device under test. For some applications, the negative lead of the function generator should attach to a negative input of the device, but usually attaching to ground is sufficient


What is a generic function?

Function generator can better be called as signal generator.It produces different types of signal like sine, saw tooth, triangular, pulse wave forms etc... can be produced.For testing any circuits which input must be a wave form like oscillator circuits function generator is used.


What is the difference between regenerator and repeater?

In packet networking, a re-generator takes the existing radio signal and boosts it whereas a repeater interprets the data and re-sends it.


What is difference between vga and lcd display?

The main difference between the tow is the signal. VGA uses an analog signal and DVI is a digital signal.


What is the difference between the pulse generator and clock generator?

clock is consider every signal time duration (on time and off time period) are must be constant.pluse is consider on time or off time period are same time period or it varies.

processing is nothing


What is the difference between generator potential and action potential in terms of their roles in the nervous system?

Generator potential is a small electrical signal that occurs in response to a stimulus, while action potential is a larger electrical signal that is responsible for transmitting signals along the nerve cell. Generator potential initiates the process of creating an action potential, which then allows for the transmission of signals within the nervous system.
