[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 ...

A signal generator is a device that produces electrical signals with different frequencies, amplitudes, and waveforms. It is a useful tool for testing and debugging electronic circuits, as it can ...

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 ...

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 project is a schematic design of and electronic circuit to generate two audio signals one in upper mid range frequency and the other is one sixth of the frequency of the first signal. The circuit ...

Do you have a need to find faulty capacitors? High ESR can lead to problems. Back in 2002, Elektor published an article about a DIY in-circuit capacitor tester, and the Elektor Lab team designed the ...

Tiny Tapeout #1 included a 4-bit CPU, a 6-bit CORDIC, an FPGA, and other tiny circuits. It seemed like an SRAM was missing, so this is my attempt to remedy that in Tiny Tapeout #2. This circuit also ...
