Microcontroller addict [Debraj] decided to make his own programmable sine wave generator ... a complete Direct Digital Synthesis (DDS) waveform generator system on a chip. If you’ve ever ...

Tom Werner / Getty Images A sine wave is a geometric waveform that oscillates (moves up, down, or side-to-side) periodically and is defined by the function y = sin x. In other words, it is an s ...

I became aware of harmonics and the sound of different shaped waveforms early in my electronics ... I have created several sine wave sources and summed them together. Seen here, the waves combine ...

This circuit can run at way beyond 100kHz, but can’t then be recommended for waveform purity! (By about 25kHz, the tri-wave has turned into a pretty good sine, anyway.) Calibration of a tuning scale ...

With the instantaneous values of the sine wave, the specific direction of the voltage shift depends on which half of the voltage waveform is affected. On a point-by-point basis, the subtracted ...

Swept sine waves let you test a device over a wide frequency range. To implement a swept sine wave with a multifunction data-acquisition card, you need to generate the data points and send them to the ...

The width of the waveform varies in proportion with the amplitude of the ... However, only a portion of the positive half of the sine wave (a pulse) is amplified because the PA tube is biased class C, ...
