The output of a digital circuit (\( y \)) is given by this expression:

\[
y = \left( AB + \overline{CB} \cdot A \right) \cdot \overline{B + C}
\]

Where \( A \), \( B \), and \( C \) represent inputs. Draw a circuit of the above equation using OR, AND, and NOT gates and hence find its truth table.
