Analog Techniques and audio



This section of the Scots Guide deals with Analogue Electronics with a special emphasis on Audio-related topics. There are also some specialist pages on the properties of cables as these relate to audio.






These days it is common for audio fans to spend time and money on purchasing ‘high performance’ cables. This area seems to have become immersed in mystery. The purpose of the pages linked below is to provide an analysis of what is often called ‘Skin Effect’ and assess its possible effect (if any) upon audio signals. The choice of materials, etc, is considered. Although the analysis is complex, the results are fairly straightforwards. If you are not familiar with the properties of transmission lines you may find it useful to look at parts 6 and 7 above before reading the pages linked below.

The following five pages deal with the use of “Twin Feeder” used to connect a power amplifier to a loudspeaker.


The page linked below provides a Java Applet that you can use to explore the effects of cable diameter, etc, upon the frequency response (in both power and time delay terms) of a twin feeder when used to link a power amplifier to a loudspeaker.
