hi guys
i am doing a baseband signal processing block for my thesis. it involves taking a 0.03-3Hz signal with DC offset, remove the offset, digitize it using an ADC, come up with algorithm for prediction of heart rate and respiration rate and display it.
right now, i am using an opamp circuit for removing the DC offset, using ADS1210 24-bit ADC evaluation board for ADC conversion and using matlab for signal processing and prediction.
the goal of the thesis is to come up with a small PCB which can do the whole thing.
i am planning to use the same circuitry for DC offset, but my apprehension is in the ADC and signal processing blocks.
my questions are:
1. can i use a DSP processor for signal processing and prediction? how difficult is it to design the accessories of the DSP processor on PCB by myself.(i have only used DSP processor using code composer studio CCS, no idea about hardware integration of DSP processor and the software programming of it).
2. can i use a 1MB ram for data acquisition from ADC?
3. do i need a separate microcontroller to look after the whole thing(ADC, memory, DSP processor, prediction, display), or can i make the DSP processor do the whole thing.
4. Finally, how complex is the project to be completed by december.
Thanks and Regards,
foxbat
