Normally one needs filters at the output to remove the high frequency components. In addition to removing the high frequency components, the filter also improves the efficiency by minimizing the high frequency signal across the load. (e.g. A pulse width modulator with zero input outputs a 50% duty cycle square wave. Even if we can't hear this, power is dissipated when it is applie… text/html 2011-01-11T14:01:31+00:00 http://www.ee.iitm.ac.in/vlsi/courses/ec330_2011/finalproject/start?rev=1294754491&do=diff You can choose to implement any one of the following. If you have a backlog of three or more experiments, you are not allowed to do the project. You should spend these three weeks on the backlogs instead. * Spectrum Analyzer * Class D audio amplifier
