| contents | Implementation of real time autocorrelation method employing the DS87C550 microcontroller A. Jiménez Cañas C. Fernández Castellanos V. Castro Castillo A. Ruiz Toledo A. Sotomayor Ortega Ingeniería Doppler Fetal Detector Real Time Autocorrelation In this work, the implementation of Real Time Autocorrelation method proposed by Takeuchi and Hogaki, isexposed. The purpose is to obtain the frequency of the fetal cardiac beats, originated from a Fetal Detector, using awide-benefits DS87C550 microcontroller. The value of frequency is showed in a LCD. The autocorrelation algorithmwas simulated in a PC to know its dynamic behavior from selected signals. A criterion to carry out the recognitionand the selection of the first conformed crest, was obtained. By means of this criterion, the period of the processedsignal is determined. Consequently, an optimized and original algorithm was created and implemented in themicrocontroller, where the value of the fetal cardiac frequency (given in pulses per minute, ppm.) is obtained each1.2 sec. In that time, two calculated values of frequency are averaged. 2005 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47401107 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.1 Vol.1 |
