The sources of noise in a signal chain can be either internal or external. Managing noise in the signal chain requires meticulous examination of each circuit in the chain to minimize noise where ...

This write-up continues the theme of my previous report: distortion correction. That blog addressed the case of steady-state distortion minimization. This month, we look at an idea that addresses the ...

A signal generator, a general-purpose piece of test equipment, performs numerous measurements for a variety of applications requiring electromagnetic wave signals as stimuli. Its roots trace back to ...

The regeneration of weak and distorted optical signals is vital in long-haul optical communication systems. Now scientists at Cornell University have developed an all-optical scheme that performs the ...

Amplifiers are specified by multiple characteristics including gain, frequency response or bandwidth, power output, linearity, efficiency, noise, and input/output impedances. In wireless applications, ...

When it’s time for your station brain trust to set, suggest, or adjust modulation for your station, you might want to bring to that meeting a copy of “The Curious Behavior of FM Receivers During ...
