Title:
VIDEO SIGNAL PROCESSING CIRCUIT
Document Type and Number:
Japanese Patent JPS6038981
Kind Code:
A
Abstract:
@ In a video signal processing circuit comprising a complementary fiher circuit (3) a subtracting circuit (27) is coupled to an input (1, 5, 33, 29) and to an output (9, 13, 25) of a filter (7). The output (9) of the filter (7) is coupled via a signal path which comprises a noise suppression circuit (43) to a combining circuit (55) which is further coupled to an output (37) of the subtracting circuit (27). In orderto compensate for the distortion occurring in the signal path via the noise suppression circuit (43) as a result of conversions (13,49), the distortion in the signal path from the output (9) of the filter (7) to the subtracting circuit is made equal thereto by applying the same conversions (13, 21).
