Consider an A/D with n = 4 and Vref- = 0V and Vref+ = 4V. Assume the A/D uses the floor of the conversion formula when turning non-integers to integers. Which of the following is/are true?
A. There are 16 possible digital outputs.
B. If the input is 0 V, the output is 0000.
C. The voltage value of LSB is 0.25 V.
D. If the input voltage is 0.95, the output is 0011.
E. The A/D analog span is 4 V.
F. If the input voltage is 1.95, the output is 1000.
