Senior Cornhusker is setting up an instrumentation to measure the change in strain on a tractor suspension over time. The strain is expected to change at a frequency of 1 Hz, but there is a strong 60- Hz noise from fluorescent light ballasts that is interfering with his measurements. First, help him to determine whether he needs a low-pass or high-pass filter in this situation. Second, design the filtering circuit by selecting appropriate values of R and C. With the selected R and C, what is the corner frequency? What are the attenuations and phase shifts for the signal and noise, respectively?
