RL High-pass Filter $$u(t)$$Instead of $$\Delta v(t)$$, we use the European symbol for voltage difference: $$u$$. The letter ‘u’ stands for “Potentialunterschied”. Trigonometry method, example 2 Assume the non-homogeneous linear differential equation of a first order High-pass LC-filter, where $$u(t)=\hat{u}\cos(\omega t)$$ is the forcing function and the current $$i(t)$$ through the inductor is the response. The differential equation for …
RLC Resonator RLC circuits are resonant circuits, as the energy in the system "resonates" between the inductor and capacitor. We will examine the properties of a resonator consisting of series circuit of an inductor (L), capacitor (C) and resistor (R), where the output is taken across the resistor.
RLC Low-pass Filter Shows the math of RLC filters and visualizes the poles in the Laplace domain. Examines and visualizes the step and frequency response.
