1, ECG signal (0.01~150Hz);
2, Heart sound signal (20~2KHz);
3, These two signal need to be synchronized ADC;
4, Just ADC these two signals, No need DSP etc;
My thought, these two signal have ADC at the same sample rate (125KHz) and then
downsample the different sample rate.
Two options ADC chips:
1, ADuCM320, It has 16 chs 14bit (1MSPS) ADC;
Can you give me better solution or suggestion?
