ERROR CORRECTING AND COMPENSATING METHOD OF D-A CONVERTING

摘要

When two sets of digital signals having different numbers of sampling are converted, if first sampling pulses having N sampling show the relation "P1<P1+1<P1+2", a value of an oversampling pulse (Qk) is established between second sampling pulses (Qk) and (Qk+1) so that the value of error (R) is decided based on the following formula, R = {(P1+1) - P1}{1 - Qk.N/M + P1} The method reduces the occurrence of errors to the minimum during a conversion of digital signals.
