I didn't explain myself fully in my previous posting.The third oscillator is used to "modulate" a VCA thus producing a amplitude modulated output which is at a varying rate.It would be even better to use 2 oscillators sweeping at different rates and each amplitude modulating one of the fixed tone oscillators.This will produce an awful did but it will produce a very varable amplitude.Why do the 2 tones need to be fixed?Would it not be better to add a 3rd sweeping tone.This would produce a harmonically rich and shifting texture with variable amplitude.It would at least be a complex waveform which should check the dynamics of an amplifier's supplies a little better. If the group wants it, I will try to make it. 73 de Conrad G0RUZ -- FAQ on WWW: http://www.contesting.com/ampsfaq.html Submissions: amps@contesting.com Administrative requests: amps-REQUEST@contesting.com Problems: owner-amps@contesting.com Search: http://www.contesting.com/km9p/search.htm |
