[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 Look at the Circuit Diagram Figure 3 depicts the schematic diagram. Because only a limited number of IOs is required, a Microchip PIC18F04Q41 14-pin microcontroller is used. It controls the DDS ...

The input resistor network in the circuit is there to turn the unipolar input signal into a bipolar signal within the IC’s ±3.5V clamping range. This is a bit of a waste of the AD8037, as it has ...

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 ...

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 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 ...

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 ...
