The major problem in this assignment was to figure out the frequency part. The calculation of the relationship between frequency
and delay took majority of the time. It was easy to make the analysis on paper, but while working it out on oscilloscope was very
time consuming as it was completely based on trial and error.
Finally The code worked properly except that for higher values of frequency the standard deviatoion is pretty high.
