Function generators create square waves, and you can vary their duty cycle—within limits typically between 15% and 85%. Outside of those limits, engineers think of the waveforms as pulses with periods ...

[Miroslav]’s project generates square waves up to 2.22 MHz and pulses with a variable duty cycle from 1-49% and 51-99%. Output is either 5 Volt TTL levels or an adjustable 0-3.38 level.

Enhancing Part 1’s pulse generator to produce a square wave output with well-shaped edges as well as pulses and continuous sine waves.

With a handful of low-leakage passive components and two high-impedance op amps, you can build a sine/square-wave generator with output period of a minute and more.

Thats where this function generator sent to us by [Mohonri]comes in. Based around a ATTiny25 and a rail to rail op amp which is able to replicate frequencies from 1Hz to about 40KHz, in square ...

This simple, robust, and low-cost signal generator, based on the LM386 power amplifier IC, provides a trio of audio-band signals with three different simultaneous outputs at the same frequency ...

Waveform Generation: The process of creating periodic or non-periodic electrical signals, such as square and triangular waves, used as fundamental components in electronic systems.
