Given the circuit to measure and display the voltage as shown in figure below: - \\( \\mathrm{ADC} \\) has 3 output bits (D2: MSB, D0: LSB) with reference voltage Vref is 8V, analog signal Vin has voltage in the range \\( [0 \\div 8](\\mathrm{V}) \\) - \\( \\quad \\) ROM has 3 address bits [A0 \\( \\div \\) 2] (A2: MSB, A0: LSB), each memory cell contains 8 bits, 8 data output bits [D7 \\( \\div \\) D0] (D7: MSB, D0: LSB) - The 7-segment LED module has 7 control signals [a \\( \\div \\) g] corresponding to the bars. The LED bar lights up when the corresponding control signal has logic ' 1 ' and turns off if logic is ' 0 '. a) Explain the operating principle of the circuit above to measure and display the voltage b) Create a table showing the dependence of the output values [D2 \\( \\div \\mathrm{D} 0] \\) of the ADC on the voltage ranges of the Vin input signal increasing from 0 to \\( 8 \\mathrm{~V} \\) c) Design the content of the memory cells of the ROM so that the 7-bar LED displays the measured voltage value
