Hi Kevin,
Thankyou for the advice, your idea was pretty much how I (think I)
constructed the posted vi. Except I weight from the mid point between
the start/end points. Still your idea would simplify the code I've
written. I am unsure if I have introduced an undesirable effect in my
code. If you
The trouble with shooting from the hip is when you shoot your own
foot! As I think about it now, I realize that my earlier suggestion
isn't the right way to go about it. My previous post described a type
of blending operation that would really only be appropriate for a
waveform that ought to be
Chris,
Please could you give me a little more information on what you are
attempting with the VI that you have attached, and whether you have
made any progress.
Kind Regards

Hi Tristan,
I need a vi to take a waveform, typicaly 200 scans over 1.5 secs, and
provide a smoothing/weighting action to join the start and end of the
wave. Waves will be played as a loop and provide continuous walking
for a biped robot. That is why it is important to smooth/join the
start/end. I
Just butting in here with a fairly simple idea that doesn't get into
any filtering theory. Basically, you would just do a weighted average
of the data points near the cycle boundary, and let the weighting
factor ramp from 0 to 100% over the set of smoothed points.
For example: suppose bn/b is
Oops, didn't proofread that my less than and greater than symbols
got interpreted as html. Here goes again on the last part:
or generally, for -10 lt;= j lt;= +10
smoothed(j) = (0.50+0.05*j)*raw(j) + (0.50-0.05*j)*raw(n-j)
smoothed(n-j) = (0.50+0.05*j)*raw(n-j) +
