Webleft half of the complex s-plane. The Bode plot of a conventional or left half-plane zero has the gain magnitude rising at 20 dB/decade above the zero frequency with an associated phase lead of 90°. This is the exact opposite of a conventional pole, whose gain magnitude decreases with frequency and the phase lags by 90°. john edwards fenton england minerva https://oakleyautobody.net
