Description

【図面の簡単な説明】
第1図は本考案の一実施例を示す入力信号レベ
ル検出回路の回路図、第2図は従来のオーデイオ
機器の入力回路図である。 図において、1……入力端子、2……電源、3
,4……出力端子、5……基準電圧源端子、6,
7……定電流源、8,9……しきい値設定用抵抗
、10,11……比較器、12……基準電圧源、
13……入力抵抗、14……帰還抵抗、15……
直流カツト用コンデンサ、16……帰還利得設定
用抵抗、17……交流増幅器を示す。なお、図中
、同一符号は同一、または相当部分を示す。
補正 平2.1.23 図面の簡単な説明を次のように補正する。 明細書第6頁第1行の「17……交流増幅器を
示す。」を「17……交流増幅器、18……交流
増幅器のバイアス抵抗を示す。」と訂正する。
