Description

The KY205 is an evolutionary digital signal processing chip for electroencephalogram (EMG) analysis. It incorporates the frequency domain analysis of the EMG signals of EMG analysis into one single chip. The technologies include EMG detection, averaging and re-sampling 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 “A=00010”) 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.
