We obtain some new results on the approximation of functions belonging to some classes of functions by $(N,p_n,q_n)(E,\theta )$ means of conjugate series of its Fourier series. These results, under conditions assumed here, are better than those obtained previously by others. In addition, several particular results are derived from our results as corollaries.
