✦ Synopsis

This paper presents a method for ECG data compression. The method is based on an orthogonal transform based on discrete Legendre polynomials. The use of such a transform provides several advantages for compressing ECG signals when compared with conventional Fourier or cosine transforms. We also have made a statistical analysis of the transform coefficients and have found that a further significant compression ratio can be achieved by using entropic coding of the transform coefficients. 1997
