This circuit simulation illustrates waveform shaping from a square wave to a sine-like wave using passive components. A 1 kHz square wave input is applied to an LC low-pass filter formed by a 50 mH inductor and a 1 µF capacitor. The filter attenuates higher harmonics of the square wave, allowing mainly the fundamental frequency to pass through. As a result, the output waveform becomes smoother and more sinusoidal. Such filtering techniques are commonly used in signal conditioning and audio appli

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
