ABSTRACT:
A cable equalizer (10) receives signals transmitted over a coaxial cable (12) at a multi-path simulator (14). The multi-path simulator (14) includes a splitter (16) that places the signal along a first path (26) and a second path (28), wherein the signal on the first path (26) is 180.degree. out of phase with the signal along the second path (28). The signal along the first path (26) propagates to a combiner circuit (18). The signal along the second path (28) propagates through a delay circuit (20) having a delay value of .tau. that determines the notch spacing of the equalized signal. The signal along second path 28 propagates from delay circuit 20 to a variable attenuator circuit (22) that determines the notch depth for the equalized signal. The combiner (18) receives the signal along the first path (26) and the second path (28) and generates an equalized signal at the output of the multi-path simulator (14). The equalized signal may be further processed by a variable attenuator circuit (24) in order to generate the final equalized signal output.
