Abstract

Optical cardiac mapping is an experimental method developed to record the electrical behavior of the heart, through the analysis of films filmed at high speed. Due to the conditions of the experiment along with the signal, a great amount of noise from different sources is stored. In this article, the comparison of the IIR type filters and the FIR filters is proposed, where the order of the filters, the phase difference and the application on the film have been compared. From this analysis it is determined that a 9th order IIR filter behaves in the same way as a 256 order FIR filter. Therefore, it can be determined that a 9th order IIR filter can be used for filtering this type of signal, reducing the computational costs in its application.
