Design a signal conditioning system to acquire and store a horizontal EOG biopotential. The bandwidth of interest is between 0.5 and 50 Hz and has peak amplitude of approximately +/-1 mV.
-a. Design and draw a block diagram (not circuit) of the signal conditioning portions (everything before ADC) of your system.
-b. Calculate the gain required to optimize you data acquisition into an ADC with desired input range of +/- 5 V.
-c. If you have a 12-bit ADC DAQ-card, what is the resolution of your signal?
-d. Is there enough voltage resolution to not require added gain on the biopotential?
