Yield-Adjusted Operation for Convolution Filter Denoising

Analytical Chemistry, 2021
A perfect denoising for measurement shall remove noise, while keeping signal truth, so it is a dual-objective optimization of the signal yield and the noise residue. The frequency difference between the noise and signal is the basis of band-limited filter denoising.
