| b. |
Using block diagrams to design a device that can measure the bio-potential
you mentioned above. Describe each block as clear as possible (including
the theory/principle, and function of each block) (15 points) |

| c. |
Every medical measurement device may suffer from different interference.
Using the device you just designed as an example to describe methods to
eliminate the noise and to improve the S/N ratio. Please list the source
of noise, the advantages, and disadvantages of each method. (20 points) |
