3.1 Quantized Random Voltages
1 Man N
This is the manual control for the integer number N in
the range 1 to 6. It defines the number of possible
states at the outputs § and $:
H The final value of N is the sum of the manual
control 1 and the external (attenuated) control
voltage applied to input !.
2 CVN
The external control voltage CVN fed into input ! is
attenuated with this control.
3 LED • 4 LED
The brightness of each LED is proportional to the
output voltage at the corresponding output § resp. $.
3.2 Stored Random Voltages
5 Man D
This is the manual control for the probability distri-
bution of the 256 states appearing at output (.
With the control set fully counterclockwise most of the
random voltages will be low magnitude but even
medium and high magnitude voltages may appear but
with smaller probability. As the control is turned to the
right (or a positive control voltage appears at the CVD
input) the distribution moves through medium to high
magnitude voltage probability. The symbol at the lo-
wer jack ( socket shows this coherence graphically
(see also fig. 1).
