EL 9000 B 15U/24U Series
By linking together a number of differently configured sequence points, complex progressions can be created. Smart
configuration of the arbitrary generator can be used to match triangular, sine, rectangular or trapezoidal wave func
-
tions and thus, e.g. a sequence of rectangular waves with differing amplitudes or duty cycles could be produced.

Applications and results:

A
Example 7
Focussing 2 cycles of 1 sequence point from 99:
One sequence point is run, configured like in
example 3. As the settings demand that the end
offset (DC) is higher than the start, the second
sequence run will revert to the same start level
as the first, regardless of the values achieved
at the end of the first run. This can produce a
discontinuity in the total progression (marked
in red) which may only be compensated with
careful choice of settings.

Example 8
Focussing 1 cycle of 2 sequence points from 99:
Two sequences run consecutively. The first
generates a sine wave with increasing ampli-
tude, the second with a decreasing amplitude.
Together they produce a progression as shown
left. In order to ensure that the maximum wave
in the middle occurs only once, the first se
-
quence must end with a positive half wave and
the second start with a negative half wave as
shown in the diagram..

Example 9
Focussing 1 cycle of 4 sequence points from 99:
Point 1: 1/4th sine wave (angle = 270°)
Point 2: 3 Sine waves (ratio frequency to se

quence time: 1:3)
Point 3: Horizontal ramp (f = 0)
Point 4: Falling ramp (f = 0)
