| Abstract: | Fetal heart rate(FHR)examination is an important part of the fetal detection and it is important for keeping pregnant women and foetuses healthy.The whole architecture of the ultrasonic Doppler system used in detecting the rate of heart is introduced.The principle for how to control the depth we want to get the signal from is described.The whole system and its performance are simulated using the SystemView software.It is shown that described using the PN code is better than using the continuous wave. |
