…(2) If the two coupling circuits are configured as AC circuits with C and R that do not transmit DC components as shown in Figure 3, it becomes a self-excited relaxation oscillator circuit that generates a square wave that alternates between metastable states for 0.7 CR seconds. This is called an astable multivibrator or astable multivibrator, and is used as a square wave oscillator or clock pulse generator. (3) If each of the two coupling circuits is configured as an AC-coupled and DC-coupled circuit as shown in Figure 4, it becomes a circuit that generates a metastable state for a certain period of time determined by the time constant of CR for each trigger input, and is used as various timers and waveform shaping circuits. … *Some of the terminology that refers to "Astable Multivibrator" is listed below.

…(2)2ヵ所ある結合回路を図3のように直流分を伝送しないCとRでそれぞれ交流的に構成すると,0.7CR秒間の準安定状態を交互に繰り返す方形波の自励的弛張発振回路となる。これを非安定マルチバイブレーターもしくはアステーブルマルチバイブレーターと呼び,方形波の発振器やクロックパルス発生器として使用される。(3)2個ある結合回路のそれぞれを図4のように交流結合と直流結合回路にすると,トリガー入力ごとにCRの時定数で定まる一定時間の準安定状態を発生する回路となり,各種のタイマーや波形整形回路として使用される。… ※「アステーブルマルチバイブレーター」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 |
