A new algorithm of active suppression of pickup noise and background in information signals in real-time measurement

A new algorithm of active suppression of pickup noise and background in information signals in real-time measurement is considered. The algorithm is based on a recurrent method of spectral coefficients calculations of noise components in an analyzed signal and a recursive algorithm of filtration for their suppression. Application of recurrent calculations in the new algorithm allows realizing dynamic spectral measurement of information signals in real time, which is not possible to execute by classical algorithms of spectral transformations due to time restrictions
