摘要： An expanding circuit is provided for a compression and expansion system. It operates to expand signals compressed in the compression system responsive to a control system of two loops, with respect to the medium-frequency component and the high-frequency component of the signals transmitted to the expanding circuit. The expanding circuit has a control system of only a single loop for varying the gain an input signal by means of control signals obtained in accordance with the levels of the medium-frequency band and the high-frequency band. An attenuation circuit imparts to signals of gains thus varied, characteristics whereby the level of the high-frequency band is attenuated more than that of the medium-frequency band.

摘要： A muting circuit comprises, substantially, a gate circuit for passing or not passing input signals and a circuit for forming a control signal for controlling the gating operation of the gate circuit. The control signal forming circuit has a circuit for detecting the level of a carrier wave in the input signal. A first time constant circuit has a very small time constant tau 1. A second time constant circuit exhibits a delay time constant of tau 2 (where tau 2>> tau 1) when a carrier wave component exists in the input and a delay time constant which becomes substantially zero when a carrier wave component does not exist. A third time constant circuit of a time constant tau 3 (where tau 3> tau 2) is with a 180 DEG phase relationship relative to the second time constant circuit.

摘要： PROBLEM TO BE SOLVED: To reduce residual image appearing in the contour shape of a mobile object which is an object on a screen when frame cyclic noise reduction is performed. SOLUTION: A motion determination part 104 selects the an alternative pixel of a larger inter-frame difference value of two alternative pixels which are separated by a plurality of pixels from a pixel of interest in left and right directions as the pixel of a motion determination object. The motion determination part 104 supplies the value of a cyclic coefficient (1-K) to a multiplication part 105 larger as the inter-frame difference value of the selected alternative pixel is larger and supplies the value of a cyclic coefficient K to a multiplication part 106 smaller. Thus, the residua image is suppressed by making the ratio of the multiplied signals of a previous frame from the multiplication part 106 added in an addition part 107 to the multiplied signals of the present frame from the multiplication part 105 smaller when the motion of the pixel of interest is larger, and noise is reduced by making the ratio larger when the motion of the pixel of interest is smaller.
