Abstract: The paper presents complete process and steps involved in FPGA based Computer Aided Diagnosis of cardiac abnormalities. Quality of the recorded heart beats is likely to be affected as the signal would be corrupted with noise. To overcome this problem Adaptive Line Enhancers (ALE) are used to eliminate the wide band noise and ALE, an adaptive noise cancellation technique is implemented with Least Mean Square (LMS) algorithm. The computation speed and noise rejection capability of DSPs do not serve the purpose. Since the FPGA is highly flexible, recursive algorithms are implemented in this device. The paper presents all the design steps involved in design of FPGA based phonocardiograph
