This is a very simple square wave generator circuit built with IC 74LS00 that can generate square signals with frequencies between 20 Hz and 1 MHz. Its stability is good enough for most applications.

I love all about electronics, circuit diagrams and crazy projects that can help us achieve almost everything our mind can conceive. I created this website and I want to invite you to participate in ...

The first time I was in school for electrical engineering (long story), I had a professor who had never worked in the industry. I was in her class and the topic of the day was measuring AC waveforms.

Fig 1. In a typical PWM controller in which the active devices are driven by a simple square wave, a Fourier representation of the clock’s frequency spectrum consists of the fundamental switching ...

Logic Noise is all about using analog circuits to make sounds. Preferably sound that will be enjoyable to hear and useful for making music. Now, the difference between music, sound, and noise is ...
