Disclosed is a method for reducing noise. The method comprises decoding a bitstream encoded with a first codec, acquiring Quantization Parameter (QP) values determined in a process of encoding the bitstream with the first codec, detecting a frame with noise by using the QP values and inputting the frame with noise to a predefined noise filter.

A two-dimensional circuit for a traveling-wave tube for millimeter and sub-millimeter electromagnetic waves synchronously interacts with an electron beam in a vacuum electronic microwave amplifier or oscillator. The circuit is a solid body having a length along the tube axis. The solid body has an electrically conductive top section and an electrically conductive bottom section. The top section is configured with a plurality of vertical vanes having a width and height and configured parallel to each other. The bottom section is similarly configured such that when the circuit is viewed in cross section along the length, the vanes on the bottom section are staggered with respect to the vanes on the top section. The top section and the bottom section are separated from each other to define a tunnel through the solid body along the length.

For distributing a signal to loads in an area, the area is divided into a plurality of regions. A respective signal point is disposed in each region for providing the signal to a load in the region. A respective diffusion point is disposed between any two neighboring signal points. The signal is initially applied to a center point of the signal and diffusion points. The signal when received at a given signal or diffusion point is transmitted to any of the signal or diffusion points within a maximum distance from the given signal or diffusion point.

A clock forwarding circuit automatically detects the delay in transmission of data between a master circuit such as a central processing unit and a slave circuit such as a semiconductor memory and forwards clocks corresponding to the delay. The master circuit includes a clock forwarding circuit which generates a clock signal. The slave circuit is coupled to the master circuit and generates a second clock signal which is synchronized with the first clock signal. The clock forwarding circuit receives the second clock signal, detects delay between the first and second clock signals and sets initial data load/unload parameters of the master circuit based on the detected delay. By forwarding clocks, the data transmission between the clocked circuits can be performed in faultless fashion independently of the delay.

A method for controlling display video data on an LCD panel having a display matrix of pixels arranged in rows and columns and having a delta structure, which includes the steps of displaying the video data in its original (unchanged) form during a first field of the video data, and displaying the video data in a modified form during a second field of the video data, with alternate (e.g., odd-numbered) lines of the video data being shifted one pixel towards a first (e.g., right) side of the display matrix. A control circuit for implementing this method generates first and second control signals for controlling the operation of a column driving circuit which drives the columns of pixels of the display matrix in the appropriate manner.
