Two ways to determine the output of a BCD digital-to-analog converter are to:

A) sum the BCD weights of all bits that are 1s, or add the decimal value for each BCD code group and multiply that value by the step size.
B) sum the straight binary weights of the input bits that are 1s, or determine the decimal value of the inputs and multiply this value by the step size.
C) divide the straight binary weights of the input bits that are 1s by the full scale value, or determine the decimal value of the inputs and multiply that value by the step size.
D) divide the full scale output value by the BCD weights of all bits that are 1s, or determine the decimal value for each BCD code group and multiply that value by the step size.

Question 2

The quantization error in an analog-to-digital converter can be reduced by:

A) increasing the number of bits in the counter and decreasing the number of bits in the DAC.
B) increasing the number of bits in the counter and DAC.
C) decreasing the number of bits in the counter and DAC.
D) decreasing the number of bits in the counter and increasing the number of bits in the DAC.
