Abstract: A method and apparatus for encoding and decoding a residual signal are provided. The encoding method includes generating a residual signal indicating a difference between a multi-channel audio signal, and an audio signal downmixed from the multi-channel audio signal and then upmixed by using additional information from the downmixed audio signal; and performing a parametric encoding method on the residual signal. The decoding method includes decoding a sinusoidal component; restoring a sine wave by using the sinusoidal component; dividing the sine wave into a plurality of sub-bands in a frequency domain; transforming the plurality of sub-bands from the frequency domain into a time domain by applying a window to each of the plurality of sub-bands; and synthesizing the plurality of domain-transformed sub-bands to restore a residual signal.

Abstract: A supporting and damping structure of a hard disk drive (HDD) that includes a housing and a printed circuit board (PCB) coupled to the housing. The supporting and damping structure includes extension parts extending from at least both edges of the PCB beyond the housing; and support members supporting the extension parts so that the HDD does not directly contact an electronic device in which the HDD is installed. The support members include dampers formed of a viscoelastic material and coupled to the extension parts and/or lower supporters and upper supporters respectively disposed on a base and a cover of the electronic device.
