Current drawing when in Pulse-Generator mode is about 60µA and 1.2mA when in Signal-Tracer mode operation. Therefore SW1 can be omitted, provided that the earclip or headphones are unplugged when the ...

The triangle wave generator circuit can generate signals with frequencies up to 300 kHz. With the component values presented in the diagram the output wave frequency is 38 kHz.

Accurate 1Hz squarewave pulses are required in digital circuits. Here's a low-cost, general-purpose 1Hz signal generator without using a crystal oscillator.

PerfectPulse pocket-sized, fast-edge signal generator and TDR provides square 32ps edge pulse. -500mV, 50Ohm output signal is square, without overshoot or undershoot. Reportedly ideal for verifying ...

Here, I would like to explain about the circuit diagram and applications of Morse code generator. Morse code is very old and versatile technique to send text messages using wireless media.

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 ...

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 ...

This is a simple function generator that works in the audio frequency range. It can be useful for amplifier testing, experimentation in digital signal processing (DSP) and electronics labs. The author ...

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 ...

This paper describes CMOS circuits generating arbitrary chaotic signals. The proposed circuits implement discrete-time continuous-state dynamics by means of analog processing in a time domain.
