Microcontroller addict [Debraj] decided to make his own programmable sine wave generator, and was able to put it together for under $40 USD. Other than low-cost, his list of requirements was as fol… ...

1. This very-low-frequency sine- and square-wave generator requires few components, but provides low-distortion outputs (derived from LTspice simulator). The output of op amp U1 is applied to the ...

We needed a handheld, battery-powered signal generator with a sine-wave output that was continuously adjustable from 100 Hz to 10 kHz. For such a wide frequency range, we selected a function ...

From its 1 Hz lower end to its 65.5 kHz upper end, the sine wave shape remains the same and the amplitude and offset I selected on the two potentiometers is consistent.

By Carlos Abascal, Harris Corp. Embedded.com (10/12/08, 12:00:00 PM EDT) Perhaps the most fundamental building block of all communication equipment is the sine wave generator. We have ample knowledge ...
