  The pointwise estimates of the deviations
$\widetilde{T}_{n,A,B}^{\text{}%}f\left(\cdot \right) -\widetilde{f}(\cdot)$
and $\widetilde{T}_{n,A,B}^{% \text{}}f\left(\cdot \right)
-\widetilde{f}(\cdot,\varepsilon)$ in terms of moduli of continuity
$\widetilde{\bar{w}}_{\cdot}f$ and $\widetilde{w}%_{\cdot}f$ are proved.
Analogical results on norm approximation with remarks and corollary are also
given. These results generalized a theorem of Mittal.
