Description: 
"多路放大電路圖" 
"	該電路圖是兩級放大電路，電路為CE-CC型，由于前級CE的輸出幅度小于后級CC的輸出幅度，因而在 輸入信號增大過程中，CE級輸出首先出現失真，根據CE級電路ACLL上U（CEQ）處右側線段較短可知，CE級輸出U01端首先出現截止失真，亦稱頂部失真。經CC電路射極跟隨輸出，Uo端同樣出現頂部被削的波形。" 
"	由于失真出現在第一級，且為截止失真，故采用靜態工作點Q上移的辦法可消除之，可以考慮減小電阻Rb1以提高Ub1的電位，進而使ICQ1增加達到工作點上移的目的。" 
"	示波器接于輸入端和第一級輸出端，明顯看到當信號增長至400V以上時，第一級輸出端的波形出現截止失真。"
