| 摘要 |
The invention covers a precision digital filter for signal samples represented in a digital form. The flow of samples xo, x1, x2, . . . xn, of the signal is split into blocks of a fixed length which are simultaneously transmitted to two circular convolution generators operating to different prime number modulos. The outputs of the generators are each submitted to a correcting device and the corresponding corrected terms are added. The added terms are each then added to a delayed prior term to generate representations of samples of a filtered signal.
