Given these signals:

Assume that they are used in a binary digital data transmission system in the following combinations. Express B and C in terms of A so that their energies are the same. Sketch each one and in each case, calculate R₁₂ in (9.16) in terms of A and T. Write down an expression for P_E according to (9.60). What is the optimum threshold in each case?

(a) s₁ (t) = s_A(t); s₂ (t) = s_B(t)

(b) s₁ (t) = s_A(t); s₂ (t) = s_C(t)

(e) s₁ (t) = s_B(t); s₂ (t) = s_C(t)

(d) s₁ (t) = s_B(t); s₂ (t) = -s_B(t)

(e) s₁ (t) = s_C(t); s₂ (t) = -s_C(t)
