ABSTRACT:
An interpolation digital filter for an audio CODEC uses a bit serial method for an audio CODEC system with a clock signal of 256 FS. The interpolation digital filter converts a 32-bits data signal of sampling frequency of 1 FS to a 32-bit data signal of the sampling frequency of 8 FS using a clock signal of 256 FS in a filter unit. Therefore, the present invention reduces the size of the system and reduces the cost.
