Design Challenges

  1. We never got around to actually low pass filtering our PWM signal. Suggest ways in which we could incorporate such a filter into our setup.
  2. A programming challenge: Write a program (in either C or assembler) which implements PWM in software (i.e. without using the timer). Compare the pulse rate and linearity you get with this program with that produced by the code in Part 5.
