An $8$ bit Analog to Digital $($A$/$D$)$ Converter is capable of accepting an input voltage of $0-10$ volts.

$$ a$.$ What is the minimum value of input voltage to cause a digital output change of the LSB

$($least significant bit$)?$

$$ b$.$ What input voltage will cause all $1$s at the ADC$$s output?

$$ c$.$ What is the digital output code if the applied input voltage is $7\mathrm{.}3$ volts
