A source has two symbols x1 and x2 with probabilities pi and pr. If a new source with four symbols is generated from the above source, the new symbol probabilities will be (∈ is a number such that 0 < ∈ < 1)

Assertion (A): SSB transmitter is generally smaller than AM transmitter
Reason (R): SSB systems mostly use combined transmitter receiver.
