Question: An APD receiver has following parameters: dark current ID = 1 nA, leakage current IL = 1 M, RL 104, bandwidth is 10 kHz.

An APD receiver has following parameters: dark current ID = 1 nA, leakage current IL = 1 M, RL 104, bandwidth

An APD receiver has following parameters: dark current ID = 1 nA, leakage current IL = 1 M, RL 104, bandwidth is 10 kHz. nA, n = 0.85, M = 100, excess noise factor F Suppose a sinusoidally varying 850 nm signal signal having modulation index m = 0.85 falls at the photodiode at room temperature (27C). Plot the following terms in decibels varying P, from -70 to 0 dBm. (a) 10 Log(S/N) Q = / . (b) 10 Log(S/N) DB = | . (c) 10 Log(S/N) Ds = / . (d) 10 Log(S/N)T= / .
