摘要：
A comprehensive analysis of the signal-to-noise ratio (SNR) in stretch processing is presented. The key is to calculate the output noise power. Based on the spectral representation theory of stochastic process, a compact formula used to evaluate the noise power is derived and then the output SNR is obtained. Further discussions for different cases are carried out. The results provide a theoretical basis for the SNR analysis.
