Ch 6 - Error Detection/correction Review Questions Study Guide Questions And Correct Answers

Error correction works by adding [blank] to transmitted message. {Ans: redundancy}True or False: use of Manchester encoding is a form of synchronization {Ans: True}A [blank] error is an isolated error condition that alters one bit but doesn't affect nearby bits. {Ans: single-bit}The [blank] is a measure of how much additional bandwidth is required to carry data at same data rate as w/o the code. {Ans: code-rate}FEC codes designed not just to detect but correct errors, avoiding need for [blank]. {Ans: retransmission}The use of coding allows reduction, referred to as [blank], and defined as reduction in decibels to achieve a specified BER of an error correction coded system compared to an uncoded system using same modulation. {Ans: coding gain}
