Title: Signal generator
Inventor: TAKAHASHI MASAYUKI
IPC: H03L7/16
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To prevent the drop in loop gain and to improve signal purity by making an output of a voltage-controlled oscillator a local input, modulating it with a modulation signal that is synchronous with a reference frequency, dividing a frequency component signal that is shifted from a local input frequency with a prescribed frequency-dividing value and controlling the voltage- controlled oscillator with a reference frequency and a phase comparison result. SOLUTION: A modulator 3 makes an output signal 6 of a frequency f of a voltage-controlled oscillator 1 a local input, makes an IQ signal a modulation signal 8 and generates f to fm frequency spectrum. A phase comparator 5 compares (f-fm) /2 frequency that has undergone n frequency division of an output signal of the modulator 3 by a signal from a frequency-dividing table 9 by a variable frequency divider 4 with a reference frequency signal 2. The comparator 5 outputs a control signal 7 from the voltage-controlled oscillator which corresponds to phase difference to be outputted and controls an oscillation frequency of the oscillator 1. With this, loop gain is largely secured, and also signal purity is improved.

Title: Scan conversion method
Inventor: SHIBUYA SHIYOUZOU
IPC: G01S7/298
Filed: 1980-02-19
Abstract: PURPOSE:To perform the coordinate conversion of the picture element position between the polar frame and the X-Y frame with a memory circuit of comparatively small capacity by employing the first and second position designating circuits which store specified data. CONSTITUTION:The first and second position designating circuits 10 and 11 are used to convert the picture element position between the X-Y frame and the polar frame. The first position designating circuit 10 stores the picture element position on the X-Y frame corresponding to the reference position of the scanning lines on the polar frame. On the other hand, the second position designating circuit 11 stores the changing amount of the picture element position of the X-Y frame following the scanning of the picture element on the polar frame. Because the number of the digits for the changing amount of the picture element position is one over several to one over ten odd of that for the picture element position, the capacity of the second position designating circuit 11 can be small.
