Which reduces the effective distance between signals in signal space?(

1.	Which reduces the effective distance between signals in signal space?(a) Time error(b) Frequency offset(c) Time error & Frequency offset(d) None of the mentionedThe question was posed to me during an interview.My question comes from Synchronization and Network Synchronization in section Synchronization of Digital Communications
Answer» Correct option is (c) TIME error & FREQUENCY OFFSET To elaborate: Time error or frequency offset or COMBINATION of both will reduce the effective distance between signals in signal space and degrade error performance.
