Device and method for interpolating frequency components of signal adaptively

摘要: A frequency interpolating device for restoring a signal similar to the original by creating suppressed component of specific band signal, approximately from input having component. In device, when is artificially created and added additional level set dynamically adaptively on basis spectrum pattern remaining signal. This setting addition done searching look-up table which stores data that causes plurality reference patterns be associated with predetermined levels. Moreover, stored in results either an aural test sample sounds or physical analysis massive data.
