VARIABLE SCRAMBLER FOR PARTITION BAND-WIDTH

摘要

an input broadband pass filtering means(1) dividing an voice broad band into several sub-bands; a frequency transition and inversion means(2) to transit or invert the divided voice band into a special band; an output broadband pass filtering means(3) which removes the unnecessary components generated in the band transition and inversion process of the divided voice band and combines the divided band again; a frequency dividing means(4) generating frequency; and an input/output control signal generating means(5) generating the Q value of the input broadband pass filtering means(1) and the output broadband pass filtering means(3), and an intermediate frequency, and the address and the control signal of a frequency look-up table of the frequency dividing means(4).
