Problem #$1$: An ADC from a datasheet specifies the following parameters:

$(1]$ Resolution $($ N $)$: $10-$bit

$[1$ Reference Voltage $(V_{\text{r}\text{e}\text{f}})$:$5V$

$]$ Integral Nonlinearity $($INL$)$: $+-2$ LSB

Using this information, what is the smallest voltage step the ADC can digitize $($i$.$e$.,$ the Least Significant Bit, or LSB size$)?(10$ points$)$

Problem #$2$: In the context of a Tri$-$State Buffer, what does $\text{'}$Z$\text{'}$ represent? $(5$ points$)$

A$)$ Logical high $(1)$

B$)$ Logical low $(0)$

C$)$ High impedance state

D$)$ Invalid state
