Consider the following $$oating point format: S EE MMM where: S $=$ sign bit EE $=$ two bit exponent stored in excess$-2$ notation MMM $=3$ bit mantissa stored in normalized form.

There is no hidden $1$ bit in the mantisaa and the base is $4.$

State whether each of the following mantissas is normalized or not:

$001$

$010$

$011$

$100$
