This is a video tutorial for Function generator. This video explains how to use function generator and how it works. The function generator is used to generate waveform. The waveform that is can be generated by function generator are sinewave, squarewave and trianglewave. Using the function generator we can adjust the frequency, amplitude and DC [...]

The schematic diagram shown in the figure below show a function generator circuit using CA3130 in the integrator the threshold detection sections. Both triangular and square-wave signal are available from this circuit’s output, ranging from 0.1Hz to 100KHz (1:1000000 ratio). This frequency adjustment is done only by a single control R1. A voltage control input [...]

Building electronic circuit tutorial (DIY: do it yourself project) is presented in this video. You can learn the basics about schematics and how they are used in electronics in this free home maintenance video.

Waveform generator is very useful in electronic experiment and design. This circuit generate sine wave oscillation, but actually we can modify the circuit to generate triangle or square wave function. Lets see its schematic diagram first, here it is: The core of this waveform generator is MAX038. This integrated circuit chip gives complete [...]
