A "Cedia" Low-Voltage Initiative Proposal

Somewhere in the mid 1980's, the NAHB Research Center in Washington was run by a guy I knew (whose name I can't seem to dig up) who had a wacky vision. His idea was to reinvent the way electrical power was distributed throughout the home. They called it Smart Home (not to be confused with the Disney movie of the same name or other stuff that uses that name now). I think it was the first use of the name.

Adoption of Wireless and Powerline Controls

One must consider all of these factors in determining whether electronic controls will replace electromechanical toggle switches. Wireless and powerline controls effectively address two factors in a positive way: absolute price and infrastructure. First, the cost of products based on these technologies is significantly less than traditional control systems installed by home systems integrators. Second, the infrastructure is already in place, so no new wires are needed.

Audio, Distortion and Feedback

Feedback is very large subject, and I am going to limit myself to some simple tutorial comments and a discussion of phenomena associated with complexity in distortion created by nonlinear gain stages, negative feedback, and the audio signal. Taken singly, these phenomena seem simple enough, but when they interact, they create distortions out of proportion to what you expect from the specifications found in product brochures. There are linear and non-linear forms of distortion. Linear distortions affect the amplitude and phase of audio signals, but don't show up on harmonic distortion analyzers as added frequency components that weren't there in the first place. Tone controls are a good example of circuits with linear distortion. Nonlinear distortions are those which add new frequency components to the original signal, either as harmonic multiples of the original frequencies or as sidebands resulting from their non-linear interaction between the original frequencies. Nonlinearities are often deliberately created in musical instruments themselves, but they are unwanted in music reproduction. We will be talking about nonlinear distortions.
