doepfer System A - 100 NOISE / RANDOM A-118
1
1. Introduction
Module A-118 (NOISE / RANDOM) is (as you might
have guessed) a noise and random voltage genera-
tor.
It produces three types of signal: white noise, colo-
red noise, and random voltage.
White and colored noise can be used as audio sour-
ces, and also, in conjunction with a sample & hold
module, as control voltages, and the random voltage is
a useful source of voltage control, especially for its low
frequency content.
The A-118 gives you the ability to mix the relative
amounts of Red (low frequency component) and Blue
noise (high frequency component) in the colored noise
output.
There are knobs to control the rate of change and
amplitude of the random voltage, and two LEDs indi-
cate the state of the voltage at any one time.

3. Controls
The A-118 produces white and colored noise. White
noise contains all audio frequencies, at random ampli-
tude. The spectrum of white noise is completely flat -
ie. each section of the sound spectrum contains the
same amount of energy (see Fig. 1).
Another type of noise is pink noise. This also contains
all audio frequencies, but with equal weighting for each
octave rather than each frequency, so the higher
frequencies get progressively quieter (see Fig. 1).
Fig. 1: Spectra of white and pink noise
1 Blue
Use control 1 to adjust the amount of blue noise (the
high frequency components) in the signal at
output " .
2 Red
Use control 2 to adjust the amount of red noise (the
low frequency components) in the signal at
output " .
3 Rate
Use control 3 to adjust the cycle time T of the
random voltage at output §. T is a theoretical figure,
because of the random voltages the module produces.
In practice, a setting of 0 on the knob means fast
changes in voltage, producing a spectrum similar to
pink noise (see Fig. 2); and 10 means slow changes
(see Fig. 3).
Remark: The random voltage is derived from the colo-
red noise output by low pass filtering. Consequently
the settings Blue and Red will affect the random
output. If desired the random voltage can be derived
from the white noise output. Please refer to the A-100
service manual or contact Doepfer if you want to
modify your A-118.
