SNR improvement based on piecewise linear interpolation
Pengfei Xu, Yinjie Jia · Journal of Electrical Engineering · 2021
Abstract Interpolation improves the resolution of the curve. Based on the stationary characteristics of the signal and the non-stationary characteristics of the noise, the theoretical proof indicates that the piecewise linear interpolation can improve the signal-to-noise ratio, which is further confirmed by simulation results.
