Learning Goal: To analyze and design a passive, first-order low-pass filter using a series RL circuit. The analysis and design will be repeated for a series RC circuit. An electrocardiogram needs to detect periodic signals of approximately 1 Hz (since the resting heart rate of a healthy adult is between 55 and 70 beats per minute). The instrument operates in an electrical environment that is very noisy with a frequency of 60 Hz. It is desirable to have a low-pass filter that will block any noise above 25 Hz. A low-pass RL filter can be built using available 120 H inductors; a low-pass RC filter can be built using available 5.0 μF capacitors; resistors of any necessary value are also available. Part B - Designing and analyzing a series RL low-pass filter Using the available 120 Hinductor, what is the value of the resistor needed to make a low-pass filter with a cutoff frequency of 25 Hz? Express your answer to three significant figures and include appropriate units. ▸ View Available Hint(s) R= Submit μA Value Units Submit Part C - Measuring the effectiveness of the series RL low-pass filter ? To measure the effectiveness of the low-pass filter design, find the magnitude of the output voltage of the series RL low-pass filter for the given frequencies.
