kmhatre 0:0981765e0a06 34 The major problem in this assignment was to figure out the frequency part. The calculation of the relationship between frequency
kmhatre 0:0981765e0a06 35 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
kmhatre 0:0981765e0a06 36 time consuming as it was completely based on trial and error.
kmhatre 0:0981765e0a06 37 Finally The code worked properly except that for higher values of frequency the standard deviatoion is pretty high.
