The diagram below shows examples of the different shapes of waveforms, selected using the ShP
sub-parameter. The random waveform takes a different random value every cycle (the cycle is
defined by the
bPM and div sub-parameters).
The trapezoidal waveform is highly configurable: examples of trapezoidal waveforms are shown
below. In the Wahoo, the shape of the trapezoid is controlled by the parameters ramp up and ramp
down, referring to the left and right sides of the waveforms shown. One cycle of the trapezoid
waveform is represented by 100 time units. The sum of ramp up and ramp down cannot exceed 100.
If the sum of ramp up and ramp down is less than 100, the remaining time is split evenly between t
a
and t
b
shown below.
