simplify this expression using boolean expression simplification.

I get an answer of 0 for the attached question, but I'm not sure if it's correct.

find the even and odd parts of two of the following two signals (a) x(t) = u(t) (b) x(1) = sin( wot +) 4 (c) x[n]= e(Nyn +#/2) (d) x[n] = d[n} %3D %3D

Find X(el") for x[n] as defined below. 3 x[n] n -3 -2 -1 0 1 3 4 6. 7

can you please go into more detail for each problem.. im not understanding how to calculate after the expression is put into the frequency domain, explain the math also how to insert it in a calculator  how did we go from30 angle -160 degree into 23.38 angle 170.55 degrees

What is the most simplified Boolean expression from the following Karnaugh map? CD AB 00 01 11 10 00 1 1 01 11 10 1 1 а. BD O b. B C D + BCD О с. В D O d. A BD+AB D

Note: Please do not handwritten.

total enegry function e^(-a|t|)

B. Find the value of x for which Inx + (Inx)2 + (Inx)3 + (lnx) += 9

x[n]= {3, 0, 0, 0, 3}
