Question

The number of errors that can be corrected without erasure information is

(a) Dmin+1

(b) Dmin – 1

(c) (Dmin+1)/2

(d) (Dmin – 1)/2

I got this question by my college professor while I was bunking the class.

My doubt stems from Error Detecting and Correcting Capability and Sampling topic in chapter Channel Coding of Digital Communications

Answer 1

Correct answer is (d) (Dmin – 1)/2

Easiest explanation: If a code has a minimum distance dmin then dmin-1 erasures can be reconstituted. The number of errors that can be corrected without erasure information is (dmin-1)/2.
