What is a simple function generator?

Simple function generators usually generate triangular waveform whose frequency can be controlled smoothly as well as in steps. This triangular wave is used as the basis for all of its other outputs. The triangular wave is generated by repeatedly charging and discharging a capacitor from a constant current source.

How can I use my phone as a generator?

Android smartphones can be used as signal generators to perform basic tasks….Function Generator app

  1. Select channel for signal (CH1 or CH2).
  2. Select waveform, such as sine, triangular or square.
  3. Select FREQ block and adjust frequency using sa lider or text input box.
  4. Select OUT from OUTPUT section, as shown in Fig.

Can function generator generate DC voltage?

Function generator has DC offset from -5 V to +5V DC. You may use low-pass filter of suitable value to get rid of ac signal and obtain DC voltage. (0.1 micro-farad capacitor with 50 ohms resistor in parallel may be connected across FG output and FG frequency set at 100Khz;keep the ac amplitude at minimum level.

What is difference between signal generator and function generator?

Signal generators make available at their outputs sinusoidal waveforms with a settable frequency or amplitude. Function generators go beyond signal generators in that they allow the generation of periodic standard functions such as sine, square, triangle, ramp up/down, dc, and noise.

What is an RF signal generator used for?

An RF signal generator is typically a signal source used to test circuits being developed for RF communications such as wireless and cellular communications, radar, electronic warfare etc. Engineers can set amplitude, frequency and apply modulations to the signal using system controls.

Can a function generator be used as a current source?

Function Generator Circuit Concepts, Part 2: Current-Source Function Generators (FGs) A third and important change is to do away with the op-amp integrator, for a current source driving a timing capacitor will produce a triangle-wave just as well, and faster. The result of these changes is the current-source FG.

How do you make an electric generator?

To make a simple electric generator, start by building a small frame out of cardboard. Next, wind the copper wire tightly around the cardboard several times, leaving 16-18 inches of wire loose on each end. Strip 1 inch of insulation off the ends of the wire and connect the wires to an electronic device.

What is function signal generator?

A signal generator is an electronic device that generates repeating or non-repeating electronic signals in either the analog or the digital domain. It is generally used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices, though it often has artistic uses as well.

What is a digital function generator?

Digital function generator: As the name indicates, digital function generators utilise digital technology to generate the waveforms. There are a number of ways in which this can be done, but the most versatile and most widely used technique for digital function generators is to use direct digital synthesis, DDS.
