    eliminate 50Hz noise in ECG using mathlab

    hi i am student.im doing research about development of adaptive digital notch filter for the removal of 50Hz power line noise in ECG.i have a sample of 50Hz noise of ECG..now i need to call the file in mathlab..how must i do it?im very new to mathlab..please help me..

    The file format (if the data can be read in a text editor) is in ASCII probably formatted.

    Such a format is unusual for such data, it would ususaly be a stream of bytes the interpretation
    of which would depend on how the data was captured, and the file would either have a header
    describing the data format or be accompanied by such a file. (Though not always, it is not unknown
    for the format to have to be deduced from a statistical anaylsis of the byte values in a file)
