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 resolu
faltersainse [42]

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

vlabodo [156]

Answer:

Impossible.

Explanation:

The ideal Coefficient of Performance is:

COP_{i} = \frac{250\,K}{300\,K-250\,K}

COP_{i} = 5

The real Coefficient of Performance is:

COP_{r} = \frac{950\,kJ-70\,kJ}{70\,kJ}

COP_{r} = 12.571

Which leads to an absurds, since the real Coefficient of Performance must be equal to or lesser than ideal Coefficient of Performance. Then, the cycle is impossible, since it violates the Second Law of Thermodynamics.
