Abstract
A unified class of linear positive operators has been defined. Using t hese operators some approximation estimates have been obtained for unb ounded functions. For particular linear positive operators these resul ts sharpen and improve the earlier estimates due to FUHUA CHENG (J. Ap prox. Theory, 1984) and XIEHUA SUN (J. Approx. Theory, 1988).
