9.2.2.1 Calculation of the Cutoff Frequencies and Gain of Stage A:
The low cutoff frequency of the bandpass filter in stage A is:
Equation 2. 
Choosing R6 = 6.81 kΩ and C6 = 33 μF, the low cutoff frequency is fClow= 0.71 Hz. The high cutoff frequency of the filter is:
Equation 3. 
For R5 = 1.5 MΩ and C5 = 0.01 µF, the high cutoff frequency is fChigh= 10.6 Hz. The gain of the stage is:
Equation 4. 
Choosing R5 = 1.5 MΩ and R6 = 6.81 kΩ, the gain of the stage A is G = 221.26 V/V (46.9 dB).
