2) (26+26)p An FM system has output signal to noise ratio, (5), a as 23.4 dB with a modulation index = 2. The transmitted signal which has a Gaussian pdf with zero mean, o variance and a bandwidth of 10kHz is passed through some successive filtering operations. The variance o is increased to 30 after the pre-emphasis filtering operation. When B = 2, the system is below than the threshold region. Therefore (5x).m should be at least 40 dB. a. What should be the maximum value of B and the corresponding transmission bandwidth to achieve operating above the threshold? What will be the corresponding (SN)? b. To achieve (Sy).. = 40dB, calculate the minimum increase in the transmitted power. Find the corresponding transmission bandwidth and the value of B. 2) (26+26)p An FM system has output signal to noise ratio, (5), a as 23.4 dB with a modulation index = 2.
