Frequency Modulation
FM Input:
The
FM Input
is a bipolar control voltage input for the
frequency parameter of the oscillator.
•
Control voltage is summed with the values set by the
Coarse
and
Fine
knobs and scaled by the
FM Attenuator
.
FM Attenuator:
The
FM Attenuator
determines the depth of frequency
modulation applied to the fundamental frequency.
•
Turning the knob anticlockwise will decrease the depth of
frequency modulation.
•
Turning the knob clockwise will increase the depth of
frequency modulation.
Lin/Exp Toggle:
The
FM Input
can be set to have a linear or
exponential FM response curve.
If the toggle is set to the left position, the FM
signal will apply with linear scaling.
If the toggle is set to the right position, the FM
signal will apply with exponential scaling.
•
If the toggle is set to exponential FM and the
FM Attenuator
is fully
clockwise, the
FM Input
will essentially track at 1V/Octave (Its
tracking may differ slightly from the calibrated
1V/Oct Input
).
