What are waveform generators?

What are waveform generators?

A waveform generator is a classification of a signal generator used to generate electrical waveforms over a wide range of signals. Common types of waveforms outputs include sine wave, square wave, ramp or triangular wave, pulse wave, cardiac pattern wave, gaussian pulse waves, arbitrary waves.

Which waveform is produced by generator?

A function generator is usually a piece of electronic test equipment or software used to generate different types of electrical waveforms over a wide range of frequencies. Some of the most common waveforms produced by the function generator are the sine wave, square wave, triangular wave and sawtooth shapes.

How do waveform generators work?

Waveform generators, like most signal generators, often have attenuators, means of modulating output waveforms, and can automatically and repeatedly sweep the output waveform’s frequency, using a voltage-controlled oscillator, between two limits determined by the user, making it quite easy to evaluate an electronic …

What do you use a waveform generator for?

Waveform Generators are used to apply specified analog signals to circuits, anything from DC signals, sine waves of varying frequencies, AM/FM modulated signals, and more.

How many types of waveform can be observed in function generator?

As we have discussed earlier that it can generate 2 different waveforms simultaneously at the two different terminals. So, it can be a useful feature as different output are required for particular applications. It provides another important feature as they have the capability of phase locking to an external source.

What are the parts of function generator?

The block diagram of function generator contains various components they are frequency control network, constant current supply source 1, constant current supply source 2, integrator, voltage comparator multivibrator, capacitor, a resistance diode shaping circuit, and two output amplifiers.

What is a waveform generator?

A waveform generator is an electronic circuit, which generates a standard wave. There are two types of op-amp based waveform generators −

How does a simple adjustable staircase waveform generator work?

The circuit diagram of a simple adjustable staircase waveform generator is shown in Fig. 1. IC1 (74HC14) is a hex inverter Schmitt trigger that generates oscillatory pulse (square wave) and gives an output clock at pin 14 of IC2 (74HC93), which is a 4-bit binary ripple counter.

How does a triangular wave generator work?

The block diagram of a triangular wave generator contains mainly two blocks: a square wave generator and an integrator. These two blocks are cascaded. That means, the output of square wave generator is applied as an input of integrator. Note that the integration of a square wave is nothing but a triangular wave.

What is a square wave generator used for?

This generator is used in digital signal processing and electronic applications. The square wave generator is also known as Astable Multivibrator or free-running and the frequency of the square wave generator is independent of the output voltage. The basic circuit diagram and working of the square wave generator are explained below.
