5 PROBABILITY DISTRIBUTION (STORED
RANDOM VOLTAGES)
The four S&H generators can be controlled as for mag-
nitude of the voltages that are more likely to be generated:
this parameter is called probability distribution, it is glob-
ally set by the Probability Distribution knob (E.1) and it can
be activated independently per each of the four S&H cir-
cuits through the four Probability Distribution Switches
(E.2, E.3, E.4, E.5).
The knob sets the magnitude of voltages which will be
generated more frequently: by default, it is set to the mid-
dle position, which means that medium voltages will be
outputted more often than high or low ones. Rotate it to
the left to raise the probability of generating lower volt-
ages, and to the right for higher ones.
Please note that this setting will not block the SH& cir-
cuits to generate different voltages than the ones whose
probability is set to be higher: they will just be generated
less frequently.
This is a significant difference, for example, from the n
Knobs function of the quantized random voltages: in that
case, the value defines the “pool” of values that may be
picked; here, on the contrary, the Probability Distribu-
tion Knob sets the magnitude of voltages that are more
likely to be generated within the “pool” selected above.
