It’s always a pleasure to find a hardware hacker who you haven’t seen before, and page back through their work. [Bettina Neumryr]’s niche comes in building projects from old electronics magazines, and ...

A library and simple project for the STM8 processor, controlling an AD9833 Waveform generator. See the wiki here: https://github.com/prosper00/STM8-AD9833-Function ...

In which we embark on a quest to forge a precise triangle wave, and use that to help set a gold standard for fake sine waves. How well will we fare? A while ago, I needed (or wanted) a pocket-sized ...

Rail-to-rail input and output (RRIO) op amps, both FET and BJT, have been around for a long time, but the possibilities they provide for versatile waveshape generation with simple circuits can still ...

Function generator or waveform generator is an integral part of electronics and used to produce various kinds of waveforms like a sine wave, square wave, Sawtooth wave, etc. We have already designed ...

In electronics, waveforms are mostly plotted against voltage and time. The frequency and amplitude of the signal can vary according to the circuit. There are many types of waveforms, like sine wave, ...

The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...

Staircase signals find many applications in the field of electronics, such as in television systems, telemetry, and analogue and digital communications. Here is a circuit illustrating the basic ...
