Abstract
In a sampling rate converter which converts a sampling frequency of digital signals sampled at a first sampling frequency into a second sampling frequency, output clocks corresponding to the second sampling frequency are counted in a cyclic fashion from an initial value to a maximum value based on periodicity of the first and second sampling frequencies. Coefficient addresses are generated in accordance with the resulting count value and a coefficient correction value which is determined in accordance with the number of counts of the maximum value and the periodicity of the first and second sampling frequencies, the number of counts of the maximum value being the number of times the output clocks are counted to the maximum value. The sampling frequency of digital signals sampled at the first sampling frequency is thus converted into the second sampling frequency with a simple construction of counting to the maximum value in accordance with the periodicity of the sampling frequencies.
