Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...

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, ...

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 ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...
