1、實用電路圖實用電路圖第第PD1PD1集集低頻放大器低頻放大器說 明電路，是一切電器的核心與靈魂。電路是有生命智慧的，產(chǎn)力的發(fā)展。將其結(jié)合到人們的創(chuàng)新創(chuàng)造中，已經(jīng)并將繼續(xù)極大地推動生實用電路圖收集了大量生活和生產(chǎn)中可直接使用的電路，希望能對人們的生產(chǎn)生活提供一點啟迪。本手冊中電路收集歷時多年，查閱大量的書籍報刊以及電器說明書，近年又在互聯(lián)網(wǎng)上廣泛搜索新發(fā)電路，以公開實用為選擇電路的基本原則，以方便學(xué)習(xí)、交流的電路圖格式繪制。為便于閱讀，本手冊大致按電路功能分為26大類，每類以功能相近再分若干小類，以小類為主每100個電路為一集。Y音頻電路 Z振蕩電路W溫度濕度T通信電路R收錄電路V電視視頻S時間
