DIGITAL SIGNAL TREATMENT REGULATION ESTABLISHING A LEGISLATIVE FILTER

摘要

PUN,8248 18.11.76 Digital signal processing arrangement provided with a wave digital filter which comprises quantizing means for limiting the signal waves present in this filter to a predetermined word length by means of "controlled rounding". By controlled rounding a limit cycle free output signal is obtained when a constant input signal is present. When the outgoing signal waves from the N-port adapter are equal to bo(j,k) and the signal waves applied to the adapter are equal to a(j,k), when b(j,k) is equal to the desired and quantized value of bo(j,k), wherein j represents the number of the port, then by means of controlled rounding bo(j,k) is now quantized in such a way that Herein c(i,j) represent constants and r the plurality of independent information signal waves.
