In this paper, we consider some classes of $2\pi$-periodic convolution functions $\widetilde{B}_p$, and
$\widetilde{K}_p$ with kernels having certain oscillation
properties, which include the classical Sobolev class as its special
case. With the help of the spectral of nonlinear integral equations,
we determine the exact values of Bernstein $n$-width of the classes
$\widetilde{B}_p$, $\widetilde{K}_p$ in the space $L^p$ for
