a. Describe a bio-potential that you are most familiar with. Including the origin of the bio-potential, frequency and amplitude range. (15 points)
   
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)
