<p>The network is for use in a television signal receiver including a source of digital video signals 10 and produces two outputs having two different amplitude versus frequency response characteristics. A comb filter 14 produces a signal having frequency bands of luminance information signals and chrominance information signals. The chrominance signal is then subjected to filtering 22 to remove vertical detail information, the output of the subtractor 26, therefore, supplies the vertical detail information which is combined with the luminance signal Y, in the adder 30. Details of the filter 22 are given in relation to Fig. 2. <IMAGE></p> |
