This audio frequency generator is a triggered signal generator. When a positive pulse of about 6 volts (minimum) is fed to the circuits input , a modulated audio signal comes out of the output. The ...

[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 ...

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 ...

An arbitrary waveform generator (AWG) is a specialized electronic test instrument that can create any waveform shape the user ...

This light chaser circuit (music-operated lighting effect generator) comprises five sets of 60W bulbs that are arranged in zig-zag fashion. The bulb sets glow one after another depending on the ...

C-Tec's new Audio Signal Generator. Leading life-safety equipment manufacturer, C-TEC, has launched an innovative new Audio Signal Generator for testing induction loop amplifiers.

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 ...

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 ...

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 realise diamond buffers have their limitations, but at least they are fast (in modest rf terms) and have good driving capability. All the transistors are on all the time, so there are no delays ...

The AG52 analog signal generator offers fast rise time square waves, lower noise floor and more for APx audio analyzers.
