1. A method for low-distortion denoising of an ECG signal by a wireless sensor device, comprising:

  • determining, by the wireless sensor device, a plurality of beats of the ECG signal for denoising using the beat selection logic unit;

    stretching, by the wireless sensor device, in time the plurality of beats by resampling the plurality of beats of the ECG signal to create a predetermined length for each beat of the plurality of beats;

    aligning, by the wireless sensor device, the stretched beats of the plurality of beats by aligning peaks of neighboring beats of the plurality of beats; and

    denoising, by the wireless sensor device, the plurality of beats using at least one ensemble averaging filter across the aligned beats of the plurality of beats.
