Unless you are a hermit or a Stylite, robust interaction with your neighbors is usually a good thing. Of course, this is not the case with broadcast transmitters, where living in isolation is usually ...

Mixed-signal printed circuit boards (PCBs) present unique challenges in high-performance applications, such as vibration analysis and other multi-channel data acquisition systems. Nonlinear ...

Let’s take an amplifier and feed it with two test signals of identical amplitude, but of two different frequencies which we will call “f1” and “f2”. Since the amplifier is non-ideal, there will be ...

Two unique, real-world cases of interference in the FM band will be discussed by David Maxson, owner of Isotrope LLC, on the Tuesday afternoon of the upcoming Broadcast Engineering Conference at the ...

noise is any unwanted disturbance of a useful signal that obscures its information content. Many different types of noise in data communication exist, and managing noise successfully requires the use ...

An additional interference problem that is significant at VHF and UHF frequencies is caused by IMPs. Any two frequencies that are allowed to mix (beat) in a nonlinear device will generate an ...

The linearity requirements of power amplifiers for use in digital cellular systems can be specified by several figures of merit, including intermodulation distortion and adjacent channel power ratio.

Distortion comes in two basic classes: Linear distortion, which is not an oxymoron; and nonlinear distortion, which includes all other distortions except noise. Noise is quite another matter and is ...
