Abstract

PURPOSE: To decrease an access time and a cycle time of a memory and to reduce the memory capacity by providing a sampling frequency converting means which uses data interpolation method between the memory and an output latch.
CONSTITUTION: A sampling frequency conversion means 4 being the application of the data interpolation method is provided after a memory 3 storing a digital pattern to interpolate inbetween low speed sampling frequency data strings area from the memory 3 at a sampling interval of n-time (n=1, 2...). Thus, even if it is required to generate a digital pattern of an over sampling frequency higher than the nyquist frequency, the digital data at each sampling period fso required at minimum by the sampling theorem is stored in the memory 3, the data is read by the sampling frequency fso, its interpolation data is generated by using the sampling frequency conversion means 4 at the post-stage, the interpolation data is generated thereby forming the oversampling digital pattern having a required sampling frequency.
