Question

Consider an ADC with 6-bit resolution. When operating in unipolar mode, the ADC supports a 0 V-to-10 V range. What is the resolution (smallest detectable difference) in volts

Answer 1

Answer:

0.156 V

Explanation:

Analog to digital converter (ADC) is used to convert an analog signal into a digital signal.

Resolution of ADC means in how many parts the signal of interest can be divided.

The resolution can be found using

Q = Full scale Voltage range/2^M

Where the full scale voltage range is 10 V and M is the number of bits of the ADC.

Q = 10/2^6

Q = 10/64

Q = 0.156 V

Therefore, the smallest voltage difference that can be detectable by this ADC is  0.156 V
