Abstract
PURPOSE:To give a free change to the characteristics of the desired frequency with a small number of elements by forming the circuit via the band elimination filter. CONSTITUTION:The output of mixer 3 is mixed with input ei at mixer 2. And this mixture ratio is changed to secure a free variation for the gain (CUT). At the same time, the output of mixer 3 is mixed with the output of band elimination filter 5 featuring transmission function E(s) at mixer 4. And this mixture ration is changed to secure a free variation for the gain (BOOST). Thus a free variation can be secured for both the central frequency and Q for filter 5.
