The circuit here is an oscillator with an unusual frequency divider that I designed when I was developing an RF system. I needed a stable and accurate 455kHz digital signal generator that used as few ...

Here is a simple frequency doubler circuit that produces a square wave output with a precise 50 percent duty cycle. There are similar circuits in the literature [References 1, 2, 3] which require ...

Gravitational waves are ripples in the fabric of spacetime predicted by Albert Einstein’s general theory of relativity, first detected in 2015. But an expected corresponding low-frequency ...
