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.
