Greetings Nick:
You should be able to get good results with your technique.
(You're essentially doing a poor-man's
Direct Digital Sythesis, when reading a pre-constructed table like you
are doing) Another way to do this is generate a sine wave, using one
of the sine generator vi's and then run it through a series of
comparators (use comparison primitive) each with a different
threshold. Add the values of each comparator output, and voila, this
is your stepped wave. In this manner, you are simulating a "flash" A/D
convertor.
Another way to do this, is to run a square wave generator (say at
400Hz) and MULTIPLY this by a sine wave at 50 Hz. This will give you
a Sine wave modulated square wave, (or vice versa, since
mathematically, they are identical!)
