Mean impulse response filter for binary signals

摘要

A circuit for filtering isolated errors from an input binary signal m is used to filter noise from binary motion classification signals in a DATV video signal processing environment A first AND gate whose inputs are connected to the input on either side of delay delta Pa detects autocorrelation in the signal m; OR gate connected to the output m' of the AND gate reproduces the input sequence of binary signals with isolated 1s or 0s removed. The provision of further AND gates and an OR gate allows the reproduction of the noise reduced input binary signal with the use of automatic enable signal AUT.
