Question

Problem 2:A first order (parallel or low pass) measurement system has a time constant of 7 = 0.25 [sec]and is to be used to monitor a simple periodic input. A

dynamic error of more than 5% cannot be tolerated (i.e. the amplitude of the output signal cannot be less than 95% of the input signal amplitude). What is the maximum allowable angular frequency of the input signal?
