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 ...

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 ...

This simple circuit generates narrow pulses at about 700-800Hz frequency. The pulses, containing harmonics up to the MHz region, can be injected into audio or radio-frequency stages of amplifiers, ...

Abstract: The Frequency and Phase that equal to Grid voltage of Reference Sinusoidal Signal is important to the network equipment and Current waveform quality. The Design of Reference Sinusoidal ...

Recently a review of a low-cost function generator appeared in Elektor Labs and for this reason I decided to also publish my personal experience with this kit. Some time ago I purchased this kit ...

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 ...
