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 ...

This circuit and its description can be found as figure 13 in the AD8037 data sheet. (from the days when ADI appended lots of lovely app notes). The second pulse generator output (left) can be found ...

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 ...

Test applications often call for a clock signal. Rather than tie up a function generator, you can build a programmable clock generator with just two ICs. You can then control the clock generator with ...

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.

A signal generator is a handy bit of kit and with the right components, it’s pretty easy to build one. Fabricating a proper signal generator probe is another matter entirely. [Frank]’s DIY ...

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 … ...
