I plan to do first steps with your ADAS1000 ECG frontend IC and I am quite a newbie in digital signal processing . I read that the ADAS1000 only has a configurable low-pass filter between the amplifier and adc.
I know from my discrete analog ecg-circuits that I had to implement also a 50Hz Notch and highpass filter. So I cant apply an these two filters discrete in hardware with the ADAS1000 but have to use DSP with the output data.
Do you have a suggestion what performance criteria I should seek to be able to process three ECG channels? So if I had to apply a Notch and a Highpass filter
simultaneously with 14bits output of the ADAS1000 I guess an Arduino or even a RaspberryPi would not work deliver enough performance for that.. Is that right?
Hi, you don't need discrete filter, you can implement filters in your microprocessor. Also suggested to use battery for powering and there is no patch to 50-60 Hz power supplies. Every thing should be isolated!
The output of adas1000 is SPI and you can connect it to arduino or every thing simply.
