Question

What is the maximum amount of quantization error that can occur in a 10bit system in the input analog voltage is from 0V to 6V?

(a) 10mV

(b) 6mV

(c) 0.5mV

(d) 1mV

I had been asked this question in an interview.

My doubt stems from Data Conversion in section Digital Communication Techniques of Avionics

Answer 1

Correct answer is (b) 6mV

Explanation: The minimum voltage step input is 6/(2^N-1) = 6/1023 =5.865mV ≈6mV. This is the maximum error that can occur during the conversion process.
