3. We discussed in class about electromagnetic interference and performed related experiments in our lab. Suppose you are designing a medical device to acquire a bio signal that has frequency

components between 1 and 500 Hz. The device will be used in an environment that is susceptible to a very high 60 Hz electromagnetic interference. What is your approach to minimize the interference without distorting the bio signal been measured? You must explain your answer. (20 pts) Be specific, clear, direct and succinct in your questions.
