DISADVANTAGE The modulation of BPSK is done using a balance modulator, which multiplies the two signals applied at the input. ... Use a right threshold value for the frame-sync block. The resulting bit stream is applied to the balanced modulator to produce DPSK signal. PSK is not susceptible to the noise degradations that affects ASK, or to the bandwidth limitations of FSK. In frequency shift keying, the carrier is modulated in such a way that high-frequency signal is achieved for high level i.e., 1 of binary data input. In FSK, two carrier signals are used to produce FSK modulated waveforms. Again, the block diagram you've shown is not that of a PSK transmitter, but that of a input data-to-bandpass signal direct converter, and not a great one at that.
