ABSTRACT:
A sampled-value code processing device in which, from the sampled-value code series input at a predetermined period, a first code series consisting of codes related to a group of sampled values determined according to a prescribed rule and a second code series consisting of codes related to sampled values other than the group of sampled values are each produced at a period longer than the predetermined period, and a filtering process for the first code series is performed by using the second code series.
