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 ...

Then feed 9-12V DC (9V typical) through the DC input jack. Here’s a pointer to generate 1MHz sine wave (and square wave) in a simple way. Short bottom two pins (Tri/Sin) of the waveform selector ...

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, ...

A recent study has mathematically clarified how the presence of crystals and gas bubbles in magma affects the propagation of ...
