Fiber-optic interferometric sensors have emerged as essential tools in precision measurement, utilising the interference of coherent light to detect minute displacements and variations in physical ...

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 ...

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, ...

The portion of the continuous RANGE of frequencies of electromagnetic radiation (i.e. oscillating electrical and magnetic energy which travels at the speed of light) used in broadcast TRANSMISSION.

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

Pass/fail testing is an analysis function of an oscilloscope that shows whether waveforms meet a set of defined criteria. The criteria are defined by a series of one or more qualifying conditions that ...
