…Therefore, the balance condition in the above equation is essentially two equations, with the real and imaginary parts being equal. For example, in the Wien bridge shown in Figure 2, there are two equations: ω 2 C 1 C 2 R 1 R 2 = 1 and C 2 R 2 = C 1 ( ZR 2 - R 1 ). In general, the balance condition includes the angular frequency ω, so the power supply must be a single sine wave to achieve balance. … *Some of the terminology that mentions "Wien bridge" is listed below.

…したがって上式の平衡条件は,実数部,虚数部がそれぞれ等しいという,実質的に二つの等式である。例えば図2のウィーンブリッジWien bridgeでは,ω2C1C2R1R2=1およびC2R2=C1(ZR2-R1)の2式となる。一般には平衡条件に角周波数ωが含まれるから,電源が単一正弦波でないとバランスがとれない。… ※「Wien bridge」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
