Question 37 3 pts Suppose bit error rate is 0.05 and the length of a packet is 50 bits. Assume bit errors happen independently. If the error correction code used in the packet can correct up to 2 erroneous bits, then what is the packet error rate (PER) after the bit error correction on the receiver side? about 21% about 46% about 7.7% about 100% Question 38 3 pts Suppose bit error rate is 0.05 and the length of a packet is 50 bits. Assume bit errors happen independently. If the packet does not use any error correction code, i.e., it cannot correct any erroneous bit, then what is the packet error rate (PER) on the receiver side? about 92.3% about 5% about 38.4% about 20.3%
