The passive RC differentiator is just a simple RC circuit where the resistor and capacitor are hooked up in series. What this does is give you an output signal that works like the mathematical process of differentiation. Basically, here the output shows how fast the input signal is changing at any given instant. In a […]

Analyzing Waveforms Generated by RC Circuits
RC circuits have the ability to create various output shapes or waveforms, depending on the type and frequency (or period) of the signal applied to the input terminals. It is similar to how the circuit “reacts” differently based on what is provided to it. In earlier lessons on RC Charging and Discharging we learned that […]
Analyzing Armstrong Oscillator Circuit with Formulas
In this post I will explain the Armstrong Oscillator which is yet another type of an LC oscillator circuit. What makes this so special is that it uses a parallel resonator circuit to store energy and then switches that energy between its two primary elements, the inductor (L) and the capacitor (C). The back-and-forth exchange of energy […]
