摘要： A low-pass filter of over-sampling type oversamples an input digital audio signal T1 and filters and removes the low frequency components of the produced aliasing noise. A spectrum analyzer circuit calculates the spectrum intensity of a predetermined band of an output signal from the low-pass filter. An expanded signal generating circuit generates an expanded signal having frequency components of the output signal from the low-pass filter. A level control circuit controls the level of the expanded signal according to the spectrum analyzer circuit. An adder adds the level-controlled expanded signal to the output signal from the low-pass filter thereby to generate a digital audio signal T2.

摘要： An electronic apparatus that transmits error information about setting of a block size to a host device includes an interface section that transmits and receives a command, a response and data to and from the host device. When the data is a predetermined length or more, the interface section executes multi-block transmission. Moreover, the electronic apparatus includes a data buffer, and a storage section that stores information about a block size. When the interface section receives a block size setting command transmitted from the host device and the block size is larger than a capacity of the data buffer, it transmits a response including error information about incapability of accepting the block size at the time which has a predetermined relation to the block size setting command.
