Q.4 In an aircraft control system, the elevator angle is controlled by the deflection angle of the lever by means of the following transfer function: 1000(s + 10) (s+ 0.1) (s

+1000) (s + 1) a) Calculate the frequency response of this system by: G(s)=- i. Finding G(jw) and the break frequencies. (5 marks) ii. Sketching the straight-line asymptotic gain curve as a function of logarithmic frequency. (6 marks) iii. Sketching the straight-line asymptotic phase curve as a function of logarithmic frequency. (6 marks) b) State whether this system behaves as a high pass, low pass, band stop or band pass filter/amplifier. What is the approximate bandwidth in rad/sec? (4 marks) c) What are the low, intermediate, and high frequency gains of this system in dB?
