Monophasic Waveform:
Represents a single forward flow component throughout the cardiac cycle.
The waveform has a rounded, blunted appearance and lacks the characteristic sharp peak.
The waveform does not cross the baseline

Biphasic Waveform:
Consists of a forward flow during systole and a reversed flow component during early diastole.
Consists of a forward flow during systole and a reduced forward flow component during diastole.
The waveform crosses the baseline

Triphasic Waveform:
Has three distinct phases: a forward flow during systole, a reversed flow during early diastole, and then a second forward flow during late diastole.
The waveform crosses the baseline
