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 ...

Frequency Modulation (or FM) synthesis is a simple and powerful method for creating and controlling complex spectra, introduced by John Chowning of Stanford University around 1973. In its simplest ...

Frequency modulation spectroscopy is a nondestructive technology for determining the water activity of pharmaceutical samples. This article discusses the various pharmaceutical applications of ...

Frequency modulation (FM) is the method of conveying informations over a carrier wave by varying its frequency .This is different from the Amplitude Modulation (AM) in which the amplitude of the ...

Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...

What are harmonics in RF systems? A given signal’s second harmonic is approximately twice the given signal’s fundamental frequency. Ideally, amplifiers are expected to have zero non-linearities in the ...
