Pulse Width Modulation (PWM) is a basic concept that is employed in many areas of electronics. PWM is a simple averaging method that is used in everything from microwave power percentages to LED ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...

After 30 years of refinements, mud-pulse systems transmit data more quickly and more accurately, through increasingly deep wellbores. Operators are pushing telemetry systems to transmit real-time data ...
