ABSTRACT:
A signal processing apparatus in a television signal transmitting system includes: a first group of delay lines for obtaining a first series of parallel signals; a first group of coefficient multipliers for weighting the first series of signals; a first adder for adding outputs of the first group of coefficient multipliers; a second group of delay lines for obtaining a second series of parallel signals; a second group of coefficient multipliers for weighting the second series of signals; a second adder for adding outputs of the second group of coefficient multipliers and one of the first series of signals; and a transmitter for transmitting output signals from the first and second adders. A signal processing apparatus in a television signal receiving system includes: an input circuit for receiving first and second signals; a first group of delay lines for obtaining a first series of parallel signals; a first group of coefficient multipliers for weighting the first series of signals; a first adder for adding outputs of the first group of coefficient multipliers and the second signal; a second group of delay lines for obtaining a second series of parallel signals; a second group of coefficient multipliers for weighting the second series of signals; a coefficient multiplier for weighting one of the first series of signals; a second adder for adding outputs of the second group of coefficient multipliers and the coefficient multiplier; and a signal composer for composing the output signals from the first and second adders.
