Q.5 (12) A binary FSK system operates with carrier frequencies of 40 kHz and 80 kHz. The bit rate is 20000 bits per second No and the transmitted signals are equally probable. The received noise is AWGN with PSD of = 1 uW/Hz and the matched filter is used in the receiver. If the receiver receives a modulated signal as shown below, 2 0.5 (1)s -0.5 0 0.51 1.5 2 3 3.5 4 4.5 5 2.5 time (sec) x 10-4 a) (2) What is the bit sequence after demodulation? State your assumption. b) (2) Write down the expression of so(t) and si(t) that represent transmission of a zero and a one, respectively. c) (2) Write down the mathematical expression of the impulse response of the matched filter. d) (2) Calculate the average energy per bit. e) (2) Sketch the block diagram of the matched filter using the correlator implementation. f) (2) Calculate the error probability.
