RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 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, ...

DYNAMIC PAGE -- HIGHEST POSSIBLE CLASSIFICATION IS TOP SECRET // SI / TK // REL TO USA AUS CAN GBR NZL (S//SI//REL) Shift to Software Demodulation in Misawa Expands Collection, Saves Money FROM: ...

Multimedia applications such as Digital TVs (DTVs), Over the Top (OTT) devices, and Set-Top Boxes (STBs) rely on digital and analog interfaces to transmit & receive audio and video content. The ...

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 ...

Analog Devices is aiming at low-power signal measurement with a combined synchronous demodulator and filter chip which allows precision magnitude and phase measurements to be made on analogue signals ...

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 ...
