SYNTHESIZER AND SIGNAL ANALYZER

Japanese Patent JP3773250

B2

PROBLEM TO BE SOLVED: To provide a synthesizer and a signal analyzer which perform edge arrangement of exact and high resolution without necessity of system clock of frequency very higher than frequency of a synthetic clock signal. SOLUTION: It comprises a system clock signal source for a system clock signal; a phase data resource for a phase data signal; an interpolater, coupled to the phase data source, which receives a system phase data signal to synchronize with a clock signal, answers every received phase data signal, and generates a contiguous edge arrangement data signal; and a phase modulator, coupled to this interpolater, which generates a clock output signal with an edge arranged at the point determined by series edge arrangement data signal.
