- 3-Phase Balanced Power Line Series Impedance and Shunt Admittance Calculator (Symmetrical Components)
For three-phase, balanced transmission lines. Reports positive, negative, and zero sequence symmetrical components of line impedance. Lines are positioned as shown below with x and y coordinates and resistivity is selected based on type of earth below the line. Method is based on Power System Analysis and Design [1] pages 197 on. Earth… Read more: 3-Phase Balanced Power Line Series Impedance and Shunt Admittance Calculator (Symmetrical Components) - Building a SAR-ADC
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 - FM vs. AM – Demodulating an FM signal using a phase-locked loop (PLL)
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)
