High frequency waveform generator is very useful in electronic experiment and design. This circuit generate sine wave oscillation, but actually we can modify the circuit to generate triangle or square ...

Provided is a downloadable “clean” sketch (Ardu_Sinewave.ino) for the sine wave generator, which is, in fact, an adapation of the wonderful work by Ken Boak and Trystan Lea.To test this, just attach a ...

The actual circuit of the generator is built with three LM386 ICs. It produces two frequencies, selectable via double-pole double-throw (DPDT) switch S1 ( Fig. 2 ) . When the switch is in position ...

The upper trace (channel 1) is VGS, a sine wave varying between 0 and –2.5 V, coming from a function generator. Fig 2. This example of results for a 2N5457 n-channel JFET shows an XY plot of the ...
