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 ...

[brmarcum] takes us back to analog building block basics with his Frequency Modulation and Demodulation tutorial. Frequency Modulation (FM) sounds simple at first, but understanding the electronics ...

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 ...

The quest for energy-efficient designs has made capacitive position encoders a hot topic. • The new mantra of position encoding is low-current drain. • Capacitive encoding is a way to realize ...

Radio over fiber transports RF signals via optical fiber, enabling low-loss distribution for wireless networks, radar systems, and radio astronomy applications.

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, ...
