PWM generation using a 555 timer IC: A triangular waveform (green) is compared with a control voltage (blue pulses) to generate a Pulse Width Modulated (PWM) signal. As the control voltage varies, the pulse width changes accordingly. The 555 timer operates in comparator mode, with components R1, R2, and C1 shaping the triangular waveform. This setup is commonly used in motor speed control, LED dimming, and signal modulation applications. #ne555 #pwm #circuitdesign #electronics #CircuitSimulation

This simulation shows how a triangle wave behaves when applied to a series R–L–C circuit, and how each component responds differently to the same input. The input triangle wave is applied at the left. A triangle wave has constant positive and negative slopes, meaning it contains a wide range of harmonics. When this signal passes through the RLC network, each element reshapes the waveform based on its physical property. The resistor output closely follows the input shape but with reduced amplitud
