At low frequencies, zeros may cause the loop gain to drop below its midband value. In such cases the servo function obtains a high-pass character with a high-pass cut-off at $$\omega_{\ell}$$. This cut-off frequency can be found in a similar way as the low-pass cut-off frequency $$\omega_{h}.$$ We now only account for the $$p$$ zeros and the $$q$$ poles with frequencies smaller than $$\omega_{\ell}$$ and use the asymptotic approximation according to (11.50) with $$p>q$$. In this way we obtain:

$\omega_{\ell}\approx\sqrt[p-q]{\left\vert \frac{b_{\ell}}{a_{k}}\frac{{\displaystyle\prod\limits_{i=k+1}^{p}}% p_{i}}{{\displaystyle\prod\limits_{j=\ell+1}^{q}}z_{j}}\right\vert }.$
