Problem 1. Design an RC filter to filter out components greater than 200 Hz. Full magnitude required for components less than 10 Hz. What did you choose as your corner frequency? What are values of R and C? Does your capacitance and resistance values conform to a preferred (available) value? What is the effect on your corner frequency if you change to the next available preferred capacitance value? Take a minute to think about how the filter design could be done in a variety of ways and how there are many trade offs (i.e. losing some magnitude on the “non-filtered” region and not completely eliminating the “filtered” region. Solution: This is a true engineering problem in that everything is not defined perfectly and could have multiple solutions. You must apply engineering judgement (a real term used in industry) First, let’s say you determine that a magnitude of 10% for 200 Hz components is sufficient reduction. Using dB=20*log M We can determine dB=20*log(0.1)=-20 dB
