Here is another example of using a CD4051 multiplexer, or more accurately a pair of CD4051s in parallel. I had lifted much of the core logic and circuits from Dave Jones designs. Again these are old designs offered from a historical perspective.
CMOS analog multiplexers were frequently used at the ETC for various purposes. Here I thought I would present a circuit I borrowed from a Dave Jones design, and slightly modified it, to build a black burst generator.
A friend asked me to rewrite a piece of code he found and was working with to create a simple info visualizer for a site. The original code came from a book by Jamie MacDonald, and as it was in AS2 I found the text of limited use, though I borrowed the bones of the XML parsing function.
