Binary phase- shift- keying (BPSK) has only two phases, 0 and p . It is therefore a type of ASK with f(t) taking the values 1 or 1 and its bandwidth is the same as that of ASK. Phase-shift-keying offers a simple way of increasing the number of levels in the transmission without increasing the bandwidth by introducing smaller phase shifts.
