Description
公差を持つRC回路の伝達関数は次式から求められ、
でカットオフ角周波数が、fgで角周波数又は限界周波数が、Rで直列抵抗26及び27の公称抵抗値が、Cでアース導線7への接続分枝にある公称並列容量値が、またTolR及びTolCで抵抗又はキャパシタンスの公差が示されている。
TolCに対して前記の公差値を仮定すると、減衰は例えば20dBの所にある。これは多くの使用にとって小さすぎ、自動車部門にとっても小さすぎる。使用される制御回路に対する精度の要求は著しく厳しく、従って特に50dB以上の要求される高い同相抑圧を生じる。
ここでC1で共通なキャパシタンス25の公称容量値が、C2で特別なキャパシタンス23及び24の公称容量値が示されている。
ここでΔ刃特別なキャパシタンス23又は24の公差を示している。キャパシタンス23及び24と25との値の差を示す容量係数n=C2/C1の導入により、公差δは次のようになる。
式(8)によれば、容量係数nは、良い近似において、大きい方の容量値を持つコンデンサの公差Δ、及びキャパシタンス23又は24及び25の直列接続の公差δのみに関係している。
n>>1に対して同相限界周波数fgGleichtaktが次のようになる。
