| Summary: | This paper describes the study on performance of digital demodulation techniques of Doppler Ultrasound Signal in practice. The technique being focused is bandpass sampling. This project includes software and hardware part to show the technique of downconversion process. First, the simulated DUS signals were sent out from PC. Then, MAX-1236 board was used as it represents bandpass sampling technique in order to sample the fetal DUS. The output signals demonstrate the performance of bandpass sampling techniques that show the limitation using this type of downcorversion. |
