Savvy is our new technology on high efficiency signal data acquisition and visualization. It implements our own system compression method to 1D signals such as ECG, audio, radar, etc. It may recover a signal from its partial samples in perceptually lossless quality. More miraculously, it even can exactly recover a high-quality signal from its partial samples in numerically lossless manner, which embodies the essential difference between system compression and interpolation methods. It may accelerate signal data acquisition by 4 times faster without loss of signal quality in many applications, including medical imaging, remote sensing, wireless communication, satellite technology and so on.
The followings demonstrate the performance of Savvy in recovering a segment of ECG signal from its partial samples.
