Example 1:
Focusing 1 cycle of 1 sequence point:
DC values for start and end are the same, also the AC amplitude. With a
frequency >0 Hz a sine wave progression of the set value is generated with
a defined amplitude, frequency and Y axis offset (DC values for start and
end).
The number of sine waves per cycle depends on the sequence point time
and the frequency. If the time was 1 s and the frequency 1 Hz, there would
be exactly one sine wave. If the time was 0.5 s at the same frequency,
there would only be a half sine wave.

Example 2:
Focusing 1 cycle of 1 sequence point:
The DC values at start and end are the same but those of the amplitude ar-
en’t. The end value is higher than the start value so the amplitude increas-
es with each new half sine wave continuously over the sequence point
time. This, of course, only if time and frequency allow for multiple waves
to be created. For instance, with f=1 Hz and time = 3 s, three full waves
would be generated, if the angle is 0°, and reciprocally the same for f=3 s
and time=1 s.

Example 3:
Focusing 1 cycle of 1 sequence point:
The DC values at start and end are not equal, as well as the AC start and
end values. In both cases the end value is higher than the start value so
that offset increases over time, but also the amplitude with each new half
sine wave.
Additionally, the first sine wave starts with a negative half wave because
the angle has been set to 180°. The start angle can be shifted at will in
steps of 1° between 0° and 359°.

Example 4:
Focusing 1 cycle of 1 sequence point:
Similar to example 1 but with a different end frequency. Here this is shown
as higher than the start frequency. This impacts the period of the sine
waves such that each new wave will be shorter over the total span of the
sequence time.
