You're Making Too Much Noise !
The subject for the August meeting is noise in RF systems. Noise effects the Signal to Noise Ratio (SNR), which in turn determines how well information is received. In radio signals, the signal-to-noise ratio is a measure of the strength of a desired signal relative to background noise (unwanted interference). In this context, the term signal rdescribes meaningful information, and noise refers to any disturbance that degrades the quality of the desired signal. This talk describes the various noise types and their effects on communications links.
