Description: PAiA 4740 Envelope Generator Design Analysis
originally publised 1974
see accompanying file: 4740adsr.gif for schematic

The PAIA 4740 Envelope Generator is built around an LM3900
Quad Norton Amplifier. Analysis of this integrated circuit is
beyond the scope of this text, but it should be sufficient to
say that a Norton Amplifier is a type of operational
amplifier that is current sensitive rather Thai voltage
sensitive.
