The normalized  AC conductance for CDW with $\omega_0 = 10^{11} Hz$, which is the typical frequency for NbSe$_3$. NbSe$_3$ under the first Peierls transition. The larger the damping coefficient, the narrower the bandwidth of conductance. The narrow band oscillation in conductance and current is also called the narrow band noise.
