A first order low pass filter (one pole, no zeros) is used to filter out high frequency noise from an audio signal. A measured response of the filter is shown in the figure below. Data for question 2 10 -10 3 5 6 time (ms) 7 8. 10 3 5 7 10 time (ms] Question 1 Determine the dominant frequency in [rad/s] of the signals shown in the figure above and determine the phase in [deg] of the filter at this frequency. Question 2 Derive the transfer function G(s) of the filter. Question 3 An input signal is defined as u(t) =0 for t 1 [s]). (Al indino
