Filed: 1982-09-27
Abstract: PURPOSE:To improve picture quality, by subtracting an output sampling and holdig a video signal from an output clamping the video signal so as to eliminate the effect of transversal noise due to random noise. CONSTITUTION:An output superimposed with a random noise appears as an input signal 11 when the DC component is lost. This input signal 11 is clamped at a clamping circuit 12 and a part of its output is sampled and held at a sample- and-hold circuit 13. The fluctuation of the clamping voltage due to the super- imposed noise is extracted at the sample-and-hold circuit 13. Then, the output from the clamping circuit 12 and the output from the sample-and-hold circuit 13 are applied to a subtraction circuit 14, where the subtraction is performed, resulting that a video signal output 15 eliminated with the transversal noise is obtained. Thus, the effect of the transversal noise due to the random noise is eliminated, allowing to improve the picture quality.

Filed: 1979-12-27
Abstract: PURPOSE:To give variable frequency and variable duty functions due to the digital system, by comparing the frequency multiple from the frequency calculating circuit with the multiple from the frequency multiple setting circuit and by feeding back the result to the variable frequency divider. CONSTITUTION:Frequency multiple 10 from counter 33 constituting the frequency calculating circuit is compared with designated frequency multiple 20 from frequency multiple setting circuit 32; and if multiple 10 is smaller, ''0'' is output from latch circuit 35. Output ''0'' if fed back to the variable frequency divider consisting of up/down counter 36 and frequency divider 37. Counter 36 is counted up according to the clock input of output ''0'', namely, at every time of generation of pulse output OUT. Since the count value is the frequency division ratio, the frequency of the signal obtained by dividing the reference clock input signal becomes lower than the just preceding frequency. As a result, the multiple value of counter 33 is increased from the preceding value up to the designated value.
