Abstract:

The cardiovascular tester based on the embedded computer is an updated version of the previous one.We developed a preamplifier circuit which can filter and amplify the pulse signal and the amplification can be easily adjusted by the embedded computer.The Proteus is adopted,on which circuit simulation and performance analysis is conducted.The results show that the simulation results and actual results are very close and meet the design requirements.Our design can improve design efficiency and save cost and is therefore worth popularizing.

Key words: cardiovascular test;preamplifier circuit;filter;amplifier;Proteus software
