	In order to use the simulation files with the extension .asc referenced in the text it is necessary to download the free programme LTspice.
	The simulation files are grouped in folders for each chapter. These can be downloaded (is this so?) into an appropriate enclosing folder. The essential files in each are the schematic .ASC files which can be run by LTspice. 
	Some schematics rely on symbols and sub-circuits created in the text. Most (if not all) can be found in the folders Mysym and Mysubs. These can be downloaded and included in the LTspice search paths. Additionally, some schematics, especially chapter 2, use commercial sub-circuits and symbols provided by device manufacturers. These too can be downloaded and must be included in the search paths.
	Some additional files are also included, but not for every schematic. The .NET files are netlist files that can be run by LTspice instead of the .ASC  file but these do not show a circuit schematic. The .PLT files are pre-determined settings for how the traces should be drawn and also annotations to the trace. They are not executable files.
