摘要: Disposed in an analog feedback amplifier are: a comparator (13) which detects difference between high-frequency signal is detected by detector (12) and (A) outputted from (11); (14) the (B) adder (18); loop filter (15) which, of output (14), passes only prescribed low-frequency band. In response to rate change pass-through (15), amplitude sensitivity governor (16) adjusts variable gain (3), thereby controlling (3).
