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 …

Getting started with FPGA design using Altera Quartus Prime 16.1 A (relatively) short introduction to compiling, simulating and uploading using the Altera Quartus development environment for the Cyclone IV on a DE0-Nano board.

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.
