Question

Which is the first type of error caused during the conversion process?

(a) sampling error

(b) interrupt signal

(c) counter error

(d) quantisation error

The question was posed to me in unit test.

My doubt is from Errors of ADC Technique in section Interfacing to the Analog World of Embedded Systems

Answer 1

Right choice is (d) quantisation error

For explanation I would say: The quantisation error is the first type of error caused in the conversion process. This error is caused because the samples are converted to a slightly higher value instead of zero.
