7-bit Hamming codeword 1010001 is received by the receiver. The bits have the locations as b1,b2b3.64,65,66,67. Determine the bit with an error Ob2 b3 O b4 b5 Question 20 if we have a digital communication system where codewords are transmitted at a rate of 20 Mbit/s. An impulse noise of duration 2 us can affect 040 © 20 O 100 2 points bits in a codeword. Question 18 If we want a block code to guarantee to detect up to 4-bit errors. What should be the minimum Hamming distance of the code? 04 05 06 09 Question 17 8 points in a digital communication system, 6 connections, each of 15 kbit's, are multiplexed using synchronous TOM. Each input unit consists of 3 bits. Determine the following The duration of an input unit (in ma) Answer The size of an output frame (in bits) Answer (4) The output frame rate (in frames) Answer (v) The output bit duration (in us) Answer SAVE
