signal-to-noise ratio (′sig·nəl tə ′nöiz ′rā·shō ) is an electrical engineering term where the proportion of desired electrical impulses are compared to that of undesired electrical impulses. 

If you were able to read the first sentence, the rest of this site will be easy. Essentially, "Signal to Noise" is a method of rating the clarity of a message. At this site, my goal is to clearly explain various facets of automotive technology. The signal from this website may be in contrast to the noise you hear elsewhere.

First the Disclaimer and the Copyright.

IMPORTANT DISCLAIMER: This website is to be viewed as a literary work, which is to be used for entertainment purposes only. These are not assorted sets of instructions to assist you in butchering, er, working on your car. Working on modern cars and/or car parts is acutely technical, and I highly recommend that you hire a professional to service your car. This website contains information about what a professional MIGHT do when working on a car, and equally as important, why they may do it. The author of this web site assumes no responsibility for inconveniences or damages resulting from use of the information supplied. The consumer or reader is individually responsible for his or her use of the information supplied and uses this information at their own risk. The author of this site has no liability for errors, omissions, or any defects whatsoever in the information or instructions, or for any damage or injury resulting from the utilization of said information or instructions.

Why do I need a disclaimer? Because some people believe efforts and enthusiasm are a viable substitute for skill, experience, and proper tools. They aren’t. If you don’t know what you’re doing, leave the job to a professional.

Being a literary work, this is subject to copyright protection.
