…A sweep signal generator sweeps the output frequency at a constant speed, allowing the frequency characteristics to be determined continuously. A function generator is also called a function generator, and can output sine waves, square waves, trapezoidal waves, pulse waves, triangular waves, etc., and is used to measure the characteristics of response to frequency and time. A frequency synthesizer uses a highly stable crystal oscillator as a reference, and uses electronic circuits for frequency division and multiplication to synthesize a digitally set frequency, and is used when particularly precise frequency requirements are required. … *Some of the terminology explanations that mention "function generator" are listed below.

…掃引信号発生器は,出力周波数を一定速度で掃引するもので,周波数特性を連続的に求めることができる。関数発生器はファンクションジェネレーターfunction generatorとも呼ばれ,正弦波のほか,方形波,台形波,パルス波,三角波などを出力することができるもので,周波数,時間に対する応答の特性測定に用いられる。周波数シンセサイザーは,高安定の水晶発振器を基準とし,分周,逓倍の電子回路を用い,ディジタル的に設定した周波数を合成するもので,周波数のとくに精密な要求に応用される。… ※「function generator」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
