ABSTRACT:
Disclosed is a digital sampling rate converter for compensating for a drop of an in-band signal, the digital sampling rate converter including a CIC (Cascaded Integrator-Comb) decimator for performing a decimation operation at a first decimation ratio based on an overall decimation ratio, for an input signal; a sub-decimator for performing a decimation operation at a second decimation ratio for a signal output from the CIC decimator; and a compensation unit for performing at least two multiplication operations and two addition operations with respect to a signal output from the sub-decimator using a lowest operation clock frequency in an assigned band.
