Title: Noise suppressing method, voice signal processing method and signal processing circuit
Inventor: DANIEL ROBERTSON
IPC: G10L21/0232
Filed: 2000-12-01
Abstract: PROBLEM TO BE SOLVED: To more effectively suppress noise in digital signals. SOLUTION: Digital signals x(t) are FFT processed, converted into Fourier components X(I) (a step 110), divided into plural frequency channels and energy E(j) in a respective channel j is computed (a step 120).
