What is a high frequency generator circuit? High frequency waveform generator is very useful in electronic experiment and design. This circuit generate sine wave oscillation, but actually we can ...

With a handful of low-leakage passive components and two high-impedance op amps, you can build a sine/square-wave generator with output period of a minute and more.

This all-analog circuit provides three key waveforms simultaneously and at the same frequency within the audio band. It is useful for evaluating audio systems, transformers, cables ...
