Antialiasing And Sync-Compensation Filter
Two dual-biquad filter chips and some external components form a multipurpose filter to reconstruct D/A converter signals. Connected to a converter's output, the filter provides antialiasing, reduces the D/A converter's quantization noise, and compensates for the "sync" function (attenuation). The...
