i doing a project of ECG and wireless Transmission.
Sensor Design Considerations
Capability to sense low amplitude signals in the rane of 0.05 - 10mV
Very high input impedance, >5 Mega-ohms
Very low input leakage current, < 1 micro-Amp
Flat frequency response of 0.05 - 150 Hz
High Common Mode Rejection Ratio
I need to do Analogue to Digital Conversion before sending to wireless Transmission Module.
My question how to choose my microcontroller?
how many bit of ADC and channels is needed?
