Standard Resistor Values: E3, E6, E12, E24, E48, E96 and AMP

Resistor values are organized into a set of different series of preferred values or standard resistor values. These standard resistor values have a logarithmically based sequence and this permits the various values to be spaced in such how that they relate to the component tolerance or accuracy. Resistor tolerances are generally ±20%, ±10% ±5%, ±2%, […]

International Radio Phonetic Alphabet: NATO Alphabet

The radio sound alphabet, more correctly be termed the radio telephony spelling alphabet is employed for unambiguously spelling out words by letter, often over radio or telephone connections Often called the radio sound alphabet, this alphabet is widely used for 2-way radio communications, and other telecommunications services to convey letters unambiguously where interference and bandwidth […]

QAM Modulation and Demodulation: Working Principle and Its Applications

In any system that uses quadrature AM, QAM modulation, there’ll be modulators and demodulators. These QAM modulation and demodulators are required to supply the potential to modulate both the in-phase and quadrature components of the modulating signal onto the carrier. QAM modulator basics The QAM modulator essentially follows the thought which will be seen from […]
