Triangle Wave Generator Circuit with a 555 Timer

Visualization of Fourier series expansion of Triangular wave (MATLAB)

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
