Also, state the gain (in dB) achieved by using the optimum frequency spacing instead of that which leads to orthogonal signals.2. Text 5.16.3. Text 5.26.4. Determine a general expression for the probability of symbol error of a general M-ary PAM signal constellation for each of the configurations shown below. Determine the power advantage gained by using configuration (a) over configuration (b).
