title: [Systems theory of the ultrasound pulsed Doppler technic for measuring blood flow. I].
abstract: Part 1 presents the signal generation of an ideal pwDoppler system in the time and frequency domain using the means of the one-dimensional system theory. Problems of realisation are ignored, but tissue properties like absorption and scattering are taken into consideration. A comparison is made with pulse echo signals from tissue.
