The two equivalent lowpass signals shown in Figure P4.10 are used to transmit a binary information sequence. The transmitted signals, which are equally probable, are corrupted by additive zero-mean white Gaussian noise having an equivalent lowpass representation z(t) with an autocorrelation function
1. What is the transmitted signal energy?
2. What is the probability of a binary digit error if coherent detection is employed at the receiver?
3. What is the probability of a binary digit error if noncoherent detection is employed at the receiver?
