(c) If the analog signal can be first passed through an amplifier circuit, compute the amplifier gain required to reduce the quantization error to 2% or less. Describe with neat sketches about the bridge circuit and amplifier diagram for this problem. (d) To do:If the applied force F-0, usually the output voltage after the A/D converter is not equal to zero, give your explanations and methods to eliminate the influence of this offset voltage.
