IPC: H04B3/06
Filed: 1995-03-10
Abstract: PURPOSE: To use a fixed decimal point processor to execute coefficient update even for a narrow dynamic range with sufficient performance in the estimation device estimating the coefficient of an adaptive acyclic filter simulating the characteristic of a signal transmission system based on a known reference signal sent to a signal transmission system whose characteristic is unknown and on a response of the transmission system. CONSTITUTION: By error information extracting part 110, information relating to an impulse response of a signal transmission system and an error of a coefficient of an acyclic filter are extracted based on a ratio of a result of adding sets of product between a difference between a response of the signal transmission system and an output of the acyclic filter and the polarity of a reference signal for a prescribed blocks to the sum of absolute values of reference signals produced for the block. Then the coefficient of the acyclic filter is updated by utilizing the information.

Title: Printer
Inventor: BORUFUUHAIDAA RAIN
IPC: B41J2/315
Filed: 1989-03-03
Abstract: PURPOSE: To make a gray gradation having a rich contrast or color graduation at the sufficiently high resolution by allowing a sheet to move ahead at only a pitch of a raster line during controlling a printing element, and giving the printing element an energy for permitting the area of dots printed to be enlarged substantially twice the area of a printing element. CONSTITUTION: A high pitch of the heat element of a thermal print head is a foundation of a dot raster. When the half pitch is made double, it becomes a pitch of dots BP in a raster line RL. The dots BP have a relatively large pitch, and is equally distributed extensively over the surface of a sheet 3. Dividing alternately the dots BP into two raster line RL causes the maximum dot area limited to the size of the heating element to be made twice. Thus, a most suitable gray gradation is obtained in the region from the almost invisible dots to the area having an area being twice as much as the heating element.
