You will design the analog hardware for a data-acquisition system to measure displacement (i.e., vibrations, distance). The range of displacement is –1 to +1 mm. Each resistance in the bridge (R1, R2, R3, and R4) is linear to displacement having a sensitivity of 10 Ω/mm. At zero displacement, all four resistors are 1000 Ω. The displacement signal exists in the 0 to 1000 Hz frequency band. With displacement equal to –1 mm, R1 1010, R2 990, R3 990, and R4 1010 Ω. With displacement equal to +1 mm, R1 990, R2 1010, R3 1010, and R4 990 Ω.
a) Create a design table with displacement R1, R2, R3, R4, bridge output (V2-V1), and ADC input.
b) A good CMRR is required. Design the analog circuit using just the single +5V supply mapping the bridge output (V2-V1) into the ADC input channel 3 (V3). You do not need to add an antialiasing analog low-pass filter. Show chip numbers, resistor values, but not pin numbers.
