For a $4$-bit Flash type Analog to Digital Convertor $\text{(ADC)}$ with full scale input voltage range $\text{"V"}$ which of the following statement$\text{(s)}$ is/are true?
- The $\text{ADC}$ requires $15$ comparators
- The $\text{ADC}$ requires one $4$ to $2$ priority encoder and $4$ comparators
- A change in the input voltage by $\frac{V}{16}$ will always flip $\text{MSB}$ of the output
- A change in the input voltage by $\frac{V}{16}$ will always flip the $\text{LSB}$ of the output
