Which of the four digital-to-analog conversion techniques (ASK, FSK, PSK or QAM) is the most susceptible to noise? go to zero at DC and hence, intuitively, one expects DPIM to incur a higher power penalty due to baseline wanders. Although return-to-zero contains a provision for synchronization, it still has a DC component resulting in “baseline wander” during long strings of 0 or 1 bits, just like the line code non-return-to-zero.
