Review of Complex Numbers (a) Simplify the following expression e j ( t + ) 1 + j (1-j ) and leave the result in polar form. (b) Simplify (cos t + j sin t )(cos2 t-j sin2 t ) and leave the result in polar form. 7. Write the following signals as a combination (sums or products) of scaled and shifted unit rectangles rect ( t ) and unit triangles ( t ) . 2-1 1-2 1 2-2-1 x(t) a) 2-1 1-2 1 2-2-1 t x(t) b)...
