A spectrum analyzer is a device that measures and displays Signal amplitude (strength) as it varies by frequency within its frequency range (spectrum). The frequency appears on the horizontal (X) axis ...

Modulation Measuring the quality of the modulation is important for making sure a system is working properly and that the information is being transmitted correctly. Understanding the spectral content ...

The worlds of computers and electronic music go hand in hand, and often there are unexpected oddities to be found, marrying the two. This Audio Spectrum Analyzer for the TRS-80 Color Computer (Radio ...

Spectrum analyzers and signal analyzers are passive receivers that display the signal in the form of easily identifiable data. Spectrum analyzers and signal analyzers display raw, unprocessed signal ...

Before we differentiate a spectrum analyzer and a network analyzer, it is important to understand what these two instruments are, and what function they perform. Thus, we give a basic overview of the ...

Back in the 1960s, when I started working in radio broadcast engineering, an oscilloscope was my “eye” on what was happening with equipment. That tool served me well and is still in daily use in my ...

Like most modern radio communications devices, wireless local-area networks (WLANs), RFID tags, and 3G cellular systems rely on complex modulations that require specialized signal-analysis ...

Just as the oscilloscope is the instrument of choice for analog electronics, and the spectrum analyzer is preferred for RF measurement, the logic analyzer is the go-to instrument for digital system ...

This article is part of EDN and EE Times’ Hot Technologies: Looking ahead to 2015 feature, where our editors examine some of the hot trends and technologies in 2014 that promise to shape technology ...
