ABSTRACT:
An interpolating non-recursive digital filter for generating output signal samples which occur at a given output sampling frequency and which are related in a predetermined way to a sequence of input signal samples has an output sampling frequency which is an integer multiple of the frequency of the input signal samples. In order to make more efficient use of the storage capacity of a storage device in the filter, multiplying coefficients representative of the difference between two samples of the impulse response which belong to different sets but to the same sampling period are used.
