IPC: H04B1/10
Filed: 1986-08-04
Abstract: PURPOSE:To obtain a picture having the best picture quality according to a reception C/N by changing the pass characteristic of a loop filter according to receiving circumstances in an FM demodulation part. CONSTITUTION:Since the deterioration of the picture quality caused by the noise is distinguished when there are a large quantity of noise such as sparkling noise SPN, etc. the band of the loop filter 11 is made narrow, disturbing waves are removed and the noise is reduced in order to prevent the deterioration of the picture quality. When there are a small quantity of noise the band of the loop filter 11 is widened and a power supporting the lock state of a PLL circuit is made to increase so as to prevent truncation noise from occuring even if a video level changes suddenly. Therefore a table TAB stores control data COND which widens the band width of the loop filter 11 if a counted value is small and narrows the band width of the loop filter 11 as the counted value gets larger and larger. Thus the circuit which automatically makes the picture quality the best according to the receiving circumstances (C/N, etc.) is constituted.
