{tab-kirat-applications title="Heart Measurements for School Events" open="true"}

Magnetic Heart Measurements

This application has been designed in order to introduce students to the idea of filters in signal progressing. It is a simplified version of the KiRAT application used to analyse biomagnetic heart signals. Using this context, students could be provided with such heart signals and apply both a highpass filter and a lowpass filter as well as experiment with detrending the signal. After successfully working with the application, the now modified signals could be used to diagnose anomalies or illnesses of the corresponding hearts.
