SQUARE WAVE GENERATOR: It's a square wave generator using an op-amp in an astable configuration. The frequency is set by POT1 and capacitor C1, and the output toggles between 0V and 5V. An LED indicates the output, and the waveform shows a clean square wave with a near 50% duty cycle. #opamp #circuitdesign #CircuitSimulation #electronics #electronicsrd #ElectronicsEducation | Electronics Education

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

In this simulation the square-wave source (1 ms period, 40% duty, 10% rise/fall) makes each element respond in its characteristic way: the resistor current follows the source almost exactly (i = v/R), so you see a square-like current that is essentially in-phase with the voltage. The inductor current cannot change instantly — it smooths the waveform into ramps and rounded peaks as it stores and releases energy (voltage impulses at edges produce gradual changes in i = (1/L)∫v dt). The capacitor c
