Interfacing to the Analog World - Technical MCQs

Q1:

One major difference between a counter-ramp A/D converter and a successive-approximation converter is:

A the counter-ramp A/D converter is much faster than the successive-approximation converter

B with the successive-approximation converter the final binary result is always slightly less than the equivalent analog input, whereas with the counter-ramp A/D converter it is slightly more

C with the successive-approximation converter the final binary result is always slightly more than the equivalent analog input, whereas with the counter-ramp A/D converter it is slightly less

D none of the above

ANS:B - with the successive-approximation converter the final binary result is always slightly less than the equivalent analog input, whereas with the counter-ramp A/D converter it is slightly more
