Title: Four-phase shift keying circuit
Inventor: SUGIUCHI SHUNICHI
IPC: H04L27/20
Filed: 1990-10-08
Abstract: PURPOSE:To easily attain rectangular adjustment and to shorten the manhour of adjustment by automatically controlling the rectangular phases of 4-phase shift keying output signal. CONSTITUTION:When a phase difference is pi/2+theta at the time of inputting two signals to a multiplier 5 and passing the multiplied signal through a low pass filter (LPF) 4, the output of the LPF 4 becomes-sintheta, and in the case of pi/2-theta, the output becomes sintheta. In the case of a rectangular state having no error angle theta, the output becomes zero. Thereby, the deviation theta of the phase difference between the outputs of two system modulators from pi/2 can be allowed to correspond to a DC component. When a DC component from a sampling circuit 3 is inputted to a controller 11 and converted into its corresponding voltage and a voltage control phase shifter 1 is controlled by the converted voltage, the modulator outputs of the two systems can be orthogonally crossed.

Abstract: PURPOSE:To enable information to be outputted in a well-balanced manner, by a method wherein when information to be outputted in a line is divided into a plurality of groups before outputting it, the spacing between the divided information groups is automatically uniformized. CONSTITUTION:The width of each column is assigned by sequentially using character keys and a 'delimiter' key, and when inputting for all columns and inputting through the 'delimiter' key are completed, a 'setting completed' key is depressed. Thereafter, quantities of spacing between the columns are calculated from the width of each column and left and right margin positions. In this case, the content of a left margin buffer 45 is subtracted from the content of a right margin buffer 46 to obtain the total width for column layout, and the content of a length buffer 45 is subtracted therefrom to obtain the total amount of spacing in the entire output width for the column layout. The total amount of spacing is divided by (number of columns + 1) to obtain the spacing lbetween adjacent one of the columns in the range from the left margin to the right margin. Actual tab positions are obtained from the spacing l.
