This calculator derives the series impedance (Z) and shunt admittance (Y) matrices for overhead transmission lines using standard power system analysis methods. It is designed for electrical engineers and students performing load flow, short circuit, or protection coordination studies. 1. Series Impedance and Carson’s Equations The self and mutual impedances of the conductors… Read more: 3-Phase Balanced Power Line Series Impedance and Shunt Admittance Calculator (Symmetrical Components)

This project was done in collaboration with my teammates in EGR334 at ASU. Introduction Many analog-digital converters work by having a successive approximation register (SAR) digitally approximate (guess) a voltage, and having an op- amp comparator compare the guessed voltage to the analog input. The output of the comparator tells the SAR whether… Read more: Building a SAR-ADC

Phase-Locked Loops (PLLs) are a widely-used building block of technologies that require motor speed controls, tracking filters, frequency synthesis providing multiple of a reference signal frequency, and frequency shift keying or FSK that decodes for demodulation carrier frequencies. For our project, we will be using a phase-locked loop to demodulate an existing frequency… Read more: FM vs. AM – Demodulating an FM signal using a phase-locked loop (PLL)
