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

This simulation demonstrates a 555 timer-based oscillator circuit operating in astable mode, generating a continuous square wave output. The circuit uses two resistors (1 kΩ and 2.19 kΩ) and a 1 µF capacitor to determine the oscillation frequency. The waveforms show the capacitor charging and discharging between 1/3 Vcc and 2/3 Vcc, which controls the 555 timer’s threshold and trigger pins. The output alternates between high and low states, producing a stable waveform at about 255 Hz, as shown i

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
