 ====== 発振回路 (Oscillation circuit) ====== ====== 発振回路 (Oscillation circuit) ======
 +発振回路（はっしんかいろ、英語: electronic oscillator）は、持続した交流を作る電気回路である。\\
 +その原理により、帰還型（きかんがた）と弛張型（しちょうがた）に分類できる。\\
 +電波の放射や、ディジタル回路におけるクロックパルス（コンピュータ（またはデジタル回路）が動作する時に、タイミングを取る（同期を取る）ための周期的な信号）の発生が代表的な用途であるが、それ以外にも、電子回路の動作の基準となる重要な回路である。\\
