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...
