This is a set of articles about a new topology for a Voltage Controlled Oscillator for electronic music applications featuring quadrature outputs and thru-zero FM capability .
This is a work in progress; I've finished three articles, and the remaining articles will be done over time.
Part 1 Discussion
Part 2 VCO Core Implementation
Part 3 The Trapezoid Waveform NEW! 1 March 2004
Part 4 LFO Waveform Generator (under construction)
Part 5 Audio Waveform Generator (under construction)
Part 6 Featureful VCO Implementation (under construction)
Part 7 Quadrature Waveform Generator (later)
Part 8 Voltage Controlled Phase Shifter (later)
Enjoy.
