D/A of course - sorry.


The octave (matlab) code posted yesterday had a bug in the harmonic
calculation. That's been fixed. In addition, I wrote another similar
octave program that will analyze an ascii string of 0's and 1's. Like the
other program, it plots the square wave that has been reconstructed from
its harmonics and it plots the magnitudes of the first few harmonics.
Here's a screen shot of a 12-bit string, "010110100000", produced by the
program:
