に供給するように構成された電圧制御減衰回路において
、現に設定されている減衰率と新たに設定された減衰率
との差に対応し、かつ誤差が大きいとき前記制御電圧の
変化を大きく制御し、かつ前記差が小さいときは前記制
御電圧の変化を小さく制御する制御手段を備えてなるこ
とを特徴とする電圧制御減衰回路。In a voltage-controlled attenuation circuit that includes a voltage-controlled attenuator and is configured to supply a control voltage to the voltage-controlled attenuator, the voltage-controlled attenuation circuit corresponds to a difference between a currently set attenuation rate and a newly set attenuation rate. , and a control means that controls the change in the control voltage to a large extent when the error is large, and controls the change in the control voltage to a small value when the difference is small.
