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 ...

All periodic signals can be described in terms of amplitude and phase. We all learned that in basic circuit theory. You surely recall having to calculate signal’s phase change when it passed through a ...

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, ...

In the late 1970s, television de- modulators became available with synchronous detectors, providing a method of monitoring the in-phase and quadrature signal components of television transmitters.

There are two radio modulation schemes everyone should know. Amplitude modulation changes the amplitude — or ‘volume’, if you will — of a carrier frequency and turns all radio into channels owned and ...

For high-speed and large-capacity optical communication applications and improvement of accuracy in microwave generation and evaluation equipment Results: NTT and their partners have developed a ...
