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, ...

[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 ...

This article is part of the Ideas for Design Series: Vol. 3, No. 7. This simple, robust, and low-cost signal generator, based on the LM386 power amplifier IC, provides a trio of audio-band signals ...

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 ...

The behavior of analog circuits can often be characterized by sweeping their inputs with a signal going across a range of frequencies and then observing the output. These sweeps can be composed of ...

Fujitsu Laboratories Ltd. today announced the development of a CMOS-based millimeter-wave signal generator capable of modulating its frequencies across a wide band of 76-81 GHz at the world's fastest ...

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 ...
