ABSTRACT:
A digital-to-analog converter which is especially suitable for use in converting digital audio data into an analog signal includes a partial signal time series data generating section for dividing a unit pulse response signal into m partial signals at a predetermined time interval T before digitally and repeatedly generating each partial signal with n items of time series numerical value data, a digital data storing section for storing m items of the latest digital data generated at the predetermined time T, a digital computing section for multiplying the time series numerical value data of each partial signal by digital data stored in the storing section corresponding to the partial signal before adding the multiplication results, and a converter for converting digital numerical value data which is the output from the digital computing section into an analog.
