H5. EXTRA CREDIT Assume that the numbers μ, r, σ1: σ2, T. T2, K, and So are given and that 0 < Ti < T2. The function σ(t) is defined as if t E [0, TI), ơı, What is the price of European call op...
1 In this problem c(K,T) denotes the price of a European call option with strike price K and strike time T, p(K,T) is the price of the identical put option, r is the risk-free rate and So is the current price of the underlying security. Which of the following are correct? i 0 <c(50,T) - c(55,T) <5e-rT ii 50e-rT <p(45, T) - c(50,T) + So < 55e-rT iii 45e-T <p(45, T) - c(50,T) + So < 50e-rT
Q.4 A position control system is shown in Figure Q4. Assume that K(s) = K, the plant 50 s(0.2s +1) transfer function is given by G(s) s02s y(t) r(t) Figure Q4: Feedback control system. (a) Design a lead compensator so that the closed-loop system satisfies the following specifications (i) The steady-state error to a unit-ramp input is less than 1/200 (ii) The unit-step response has an overshoot of less than 16% Ts +1 Hint: Compensator, Dc(s)=aTs+ 1, wm-T (18 marks)...
