Analog quiz 6

For the signal flow graph of the given figure, consider the following statements 1. It has three forward paths 2. It has three individual loops 3. It * has two non touching loops Out of above the correct statements are Xg 1,3 O 1, 2, 3 O 1,2 O 2, 3 O

2. Consider Figure 1.a) Find and draw an orthonormal basis function set for the signal set given in Figure1a. Apply Gram-Schmidt orthogonalization procedure and show your calculationsteps. Describe the signals in terms of the orthonormal bases. Draw the signalconstellation diagram.b) For Figure 1b, using the orthonormal basis set you derived in Question 2a, describethe signals in terms of the orthonormal bases. Draw the signal constellationdiagram.c) Combine the signal sets in Questions 2a and 2b. You must add another signal setto this combination, so that sum of all the signals ultimately form an efficient 8-QAM modulation scheme. Find and draw this signal set and also describe them interms of the orthonormal bases.
