(6) A linear time-invariant (LTI) system consists of 2 LTI systems that are connected in cascadê. Their impulse responses are Sa(10nt) and Sa(20nt). The input signal to above system has an autocorrelation of 58(1). Examine the above system and answer the following. (1) Determine the power transfer function. (6 marks) Derive the output power spectral density and sketch the same. (4 marks) (11)
