 +-----
 +
 +You can find the solution of the assignment [[http://www.cse.yorku.ca/~mohammad/3451F13/docs/Assignment 1- sol.pdf|here]].
 +
 +-----
 +Corrections: 
 +
 +Section 1.7 question (iv) 
 +-> e^(-2t) must be squared before performing the integration when calculating the energy of the signal.
 +
 +-> The correct final answer for the energy should be 1/4 
 +
 +
 +Section 1.8 question (i) 
 +
 +-> The correct formula is used in the solution (i.e. (A^2)/2 + (B^2)/2 but the final answer 
 +is wrong)
 +
 + 
 +-> Final answer should be: %%((%%1/2)^2)/2 + %%((%%1/2)^2)/2 = 1/8 + 1/8 = 1/4 
 +
 +Section 1.8 question (v) 
 +-> 2^k must be squared before performing the summation when calculating the energy of the 
 +signal.
 +
 +
 +-> The correct final answer for the energy should be 1,398,106 
 +
 +
 +Section 1.15 question(i)
 +
 +-> The original question should be: x[k] = sin(4k) + cos%%((%%2pi*k)%%/(%%3))
