Q. The following logic circuit represents

A) NAND gate with output $O$= $\overline{X} + \overline{Y}$
B) NOR gate with output $O$= $\overline{X + Y}$
C) NAND gate with output $O$= $\overline{X \bullet Y}$
D) NOR gate with output $O$= $\overline{X} \bullet \overline{Y}$
Explanation

(b) The given question is based on bridge rectifier. This is the most widely used full wave rectifier. It makes use of four diodes $D_{1},D_{2},D_{3},D_{4}$ connected in the four arms of a bridge.

Bridge rectifier does not required a centre tapped transformer. It has several advantages over wave rectifier.
