37K views · 609 reactions | A DC voltage doubler circuit using a 555 timer works by generating a square wave in astable mode to drive a charge pump made of diodes and capacitors. In simulation, this setup charges and transfers energy in phases, effectively producing nearly double the input DC voltage at the output. It's useful for low-power applications needing a higher voltage. #doubler #Electronics #ElectronicsEducation #electronicsrd | Electronics Education | Facebook

73K views · 839 reactions | This Simulation shows a square wave in both time and frequency domains. In the time domain, sharp edges include harmonic content, while in the frequency domain, these appear as distinct peaks at odd harmonics. This illustrates how complex signals are built from simpler sine waves. #electronicsrd #ElectronicsEducation #FFT | Electronics Education | Facebook

A square wave is not a single signal but a combination of multiple sine waves added together at specific frequencies and amplitudes. This simulation demonstrates that concept using an op-amp based summing amplifier. Five sinusoidal inputs, each representing a harmonic component of a square wave, are applied through equal input resistors. The operational amplifier linearly sums these signals and produces a composite output waveform. The lowest-frequency harmonic defines the overall shape, while h
