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 to the resulting count value and a coefficient correction value in accordance with a number of counts of the maximum value and the periodicity of the first and second sampling frequencies, the number of the maximum value which is a number of times of counting 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 to the periodicity of the sampling frequencies.
