Calculating Capacitance from Two Voltage Measurements

This post explains the math behind a very specific situation: charging a capacitor from 0 V to a fixed voltage through a resistor of known value. The time at which the capacitor begins charging is...


Telecommunication Basics Part 3: Error Correction Coding

Error correction coding or "coding theory" is the means by which data transmitted over a noisy medium is recovered at the receiver. ECC works by adding redundant bits to the data being transmitted...


Telecommunication Basics Part 2: Modulation

In December 2012, I was award an MS in ECE. My focus was in telecommunications. After learning this, an acquaintance asked me to explain what telecom is. I think I might have gotten the highlights...

Buck Converter Concepts Part 3 of 3: Switching Regulators

Buck converters work by switching on and off at very high frequencies. Examine the schematic below. The circle on the left is a voltage source at say 12V. The rectangle on the right is a load that...
