DIGITAL SIGNAL PEAKING APPARATUS WITH CONTROLLABLE PEAKING LEVEL

摘要

A digital signal peaking apparatus combines input digital signals with filtered and scaled representations thereof to produce controllably peaked digital signals. A digital filter produces the relatively higher frequency components of the input digital signals which are controllably scaled by a digital multiplier in accordance with a multiplier coefficient. A control arrangement develops the multiplier coefficient having a value determined in accordance with the peak magnitude of the higher frequency components of the input digital signals relative to the value of a peaking control level signal.
