Title: Filter circuit
Inventor: SHIBATA TATSUO
IPC: H04N5/21
Filed: 1991-05-29
Abstract: PURPOSE:To obtain a stable picture without picture disturbance by using a selector provided on an output section so as to select a digital composite video signal at write. CONSTITUTION:A coefficient write control means 4 outputs a coefficient write enable signal W and the signal is outputted to a transversal filter 2 and a selector 8. The filter 2 writes a coefficient Ci outputted from an arithmetic means 7 by using the signal W. When the output of the filter 2 is unstable, the selector 8 does not select an output of the filter 2. Then the selector 8 selects a digital composite video signal converted at an A/D converter means 1 from an input terminal IN. and outputs the signal to a D/A converter means 3. Moreover, when the signal W from the control means 4 is lost, the coefficient Ci is no to the filter 2, the selector 8 selects an output of the filter 2. Then disturbance of the picture is eliminated and a stable picture is obtained.
