PROJECT TITLE :
Parameter-Varying Notch Filter With Tunning Mechanism For The Acquisition Of Electrocardiographic Signals Subject To Powerline Interference
Power line interference could be a common drawback in the acquisition of electrocardiographic signals. Different techniques have been used in order to cancel power line interference such as adaptive filters with a top quality issue. Each of these techniques are specific disadvantages like massive transient response or the shortcoming to track changes in the frequency of the facility line interference for its removal. In this text, another filtering method is presented. This methodology is capable to track deviations of the frequency associated to the power line interference, keeping a slim stop band with a reduced transient response. The filtering strategy was implemented with the aid of a chpKIT max32 as a discrete-time system. Measurements results make sure the adequate operation of the proposed discrete-time filter
