It is difficult to get noise free signal in microwave frequency range of 30 gigahertz and above, Fujitsu has announced millimeter wave low noise signal generator circuit for automotive radar and other ...

I have wanted to make a pulse generator for years. I know you can buy perfectly good ones, but not if you want non-overlapping outputs to drive the mosfets in synchronous-rectified dc-dc converters.

[Debraj] needed a simple signal generator for a project he was working on, but didn’t have one handy. He found that the easiest and cheapest way to get clean, reliable signaling was by using something ...

A very simple thyristor signal generator circuit which uses a single thyristor, two resistors, a capacitor and a mini-loudspeaker. Once the circuit is switched ti a current source, current flows ...

Test and instrumentation applications may need a series of spaced, identical low-frequency sine wave with well-defined phase differences between them. This simple circuit provides eight such outputs ...

This sawtooth generator circuit use 741 IC and is used as a musical sound synthesizer. The sawtooth input signal is continously changed through P2 to a waveform with a doubled frequency and half ...

Using a single op amp and a properly selected resistor, this white-noise generator provides flat output versus frequency and speeds testing of circuit performance. The behavior of analog circuits can ...

The Eico model 377 was a pretty common audio signal generator. [The Radio Mechanic] picked one up from 1956 that was in reasonably good shape, and shares a teardown and repair of the unit that you can ...
