Hello,
I hope I got it right, what you are trying to do. Your goal is to ramp
up to the starting point of a sine signal and at the end of the sine
signal ramp down to zero.
1. The duration of the Ramp is determined by the time between samples
(dt) and the number of samples. So dt=0,001 and 1000 samples gives a
duration of 1 second.
2. The ramp functions are defined by start, end and number of samples.
For the first ramp, start would be zero (or other), end would be the
first value of the sine signal, wich can be indexed with time zero. For
the second ramp start would be the last value of the sine signal ,
which can be indexed with the duration of waveform of the sine signal.
End would be zero. In both cases the number of samples is 1000 (with
dt= 0,001)
The changes are shown in the appended VI.
