The first includes the main double pendulum-based oscillator and two sub oscillators. The double pendulum combines a sine ...

So we’ll look into an entirely different filter, the Twin-T notch filter, that turns out to be sharp enough to build a sine-wave oscillator on, and tweakable enough that we’ll make a damped ...

Part 1 shows how to make an oscillator with a pitch that is proportional to a control voltage. Part 2 shows how to modify the circuit for use with higher supply voltages, implement it using discrete ...

However, the 28.8 MHz oscillator onboard isn’t as stable ... The Fourier series tells you that a square wave is an infinite sum of sine waves. One sine wave is at the fundamental frequency ...

An audio waveform theoretically comprised of an infinite set of odd harmonic sine waves. It is often used in ... See: Fourier Theorem, Oscillator. Compare: Pulse, Sawtooth Wave. Triangular wave, its ...

An audio waveform theoretically comprised of an infinite set of odd harmonic sine waves. It is often used in sound synthesis. See also: Fourier Theorem, Law of Superposition, Oscillator, Switch.
