pressure pulse differentiation pressure pulse differentiationthe processing of a pressure pulse signal so that the output depends upon the rate of change of the input, yielding dP/dt (pressure) or, for noninvasively recorded pulses, dD/dt (rate of change of displacement).pres·sure pulse dif·fer·en·ti·a·tion (presh'ŭr pŭls dif'ĕr-en'shē-ā'shŭn) The processing of a pressure pulse signal so that the output depends on the rate of change of the input, yielding dP/dt (pressure) or, for noninvasively recorded pulses, dD/dt (rate of change of displacement). |
