Amplifiers and Nonlinear Systems

January 26, 2015 by 3200 Creative

Nonlinear System Amplification

Amplifiers often exhibit nonlinear behavior, especially when pushed to maximum gain.  Nonlinearities introduce distortion into the amplifier output. In particular, intermodulation distortion results at sum and difference frequencies of the input.  Nonlinear distortion is very problematic for communication systems, but is exploited creatively by electric guitarists. Find out more and listen to examples of distortion at Nonlinear […]

Nonlinear Systems Astrophotography

Ever wondered how NASA and hobbyists can produce such stunning images of the night sky?  A key element in producing visually compelling images is applying a nonlinear system to the image data collected by both amateur and professional imaging equipment.  This is known as "stretching" the image and has the effect of exaggerating differences between relatively low light […]
