Quicker transmission of electrocardiogram signals through channels like across wireless networks, telephone networks, hospital networks is not possible without compressing them. Here I implement an algorithm for ECG (electrocardiogram) signal compression based on Delta Coding and LZW (Lempel–Ziv–Welch) encoding. To carry out compression, real time ECG data has been recorded through EKG sensors and Labview. Since the recorded signal was analogue it was first converted to digital by applying Savitzky Golay Filter, uniform sampler and quantizer sequentially. Then the signal was compressed using delta coding and LZW coding. Then the compressed signal was decompressed and then further converted to analogue. Finally the reconstructed signal was compared with the original signal. This was done for six different analogue samples. The compression ratios and the reconstruction errors for all were calculated....
