Description

The KY202 is an evolutionary digital signal processing chip for heart rate variability (HRV) analysis. It incorporates the state-of-the-art technologies of heart rate variability analysis into one single chip. The technologies include R point detection, noise rejection, interpolation in time domain, and fast Fourier transform in frequency domain. The operation is fully automatic, and no command is needed. The input data can be in the form of analog waveform or digital series through a UART input. The analysis result is formatted in ASCII codes (such as “HR=85”) and output through a standard UART output. The chip has a very small size (5 x 5 mm2) and very low power consumption (< 4 mA), and is suitable for various hand held applications.
