i have a quantum circuit which is

it is combination of two hadamarded gates and one CNOT gate and my input state is (1/sqrt(2))*(|00>+|11>)
what is the basis unitary matrix for these combination gates and what is the out put state

-------(H)---------|-----------
|
|
------- (H)-------(+)-----------

NOTE: --(H)-- is hadamared gate and
|
and -- (+)-- is CNOT gate
