You can build a simple 1KHz square wave generator using a few components and the LM3909 that is useful for testing audio equipment. It is powered from a single 1.5V battery cell and the maximum ...

I needed a stable and accurate 455kHz digital signal generator that used as few components as possible. The signal generator also had to have a duty cycle of, or very close to, 50% to nullify or ...

The square-wave signal is available at the outputs SQW1 (non-adjustable amplitude) and SQW2 (adjustable amplitude with the potentiometer P2). The sinusoidal signal at point B is connected via ...

A signal generator that can produce the usual sine, square, and triangle waves is handy and has been a staple of electronic benches for decades. Being able to craft custom signals opens up new ...

When we use a microcontroller to flip a few GPIOs or talk SPI to a peripheral chip, we are often overlooking that it will usually contain an array of built-in peripherals that were once the preserv… ...

Measurement Setup For this experiment, a 1.5-GHz square-wave signal generator is used as the clock source for a 12-GHz pattern generator.

Complex sound Unlike the pure tone of the current high-pitched alarm, the lower-pitched alarm was a square wave signal, which carries a number of frequencies along with the dominant frequency.
