Digital Electronics

Q1:

A 12 bit ADC is employed to convert an analog voltage of zero to 10 volts. The resolution of the ADC is

A 2.44 mV

B 24.4 mV

C 83.3 mV

D 1.2 V

ANS:A - 2.44 mV

Full scale measurement range = 0 to 10 volts. ADC resolution is 12 bits: 2^12 = 4096 quantization levels. ADC voltage resolution is: (10-0)/4096 = 0.00244 volts = 2.44 mV.
