Suppose x(t) is the continuous-time function given by x(t) = 1 on the interval [0; 1] and x(t) = 0 elsewhere. a) Calculate the c

borishaifa [10]

Answer:

a) X( w ) = 1 /jw - e^-jw / jw

b) X1(t) = 1 for 0.5

X1(t) = 0 for elsewhere

Step-by-step explanation:

x(t) continuous time function = 1

interval ( 0,1 ) also x(t) = 0 outside the given interval

a) Determine the continuous time Fourier transformation of x(t)

x( t ) = u(t) - u(t - 1 )

x ( w ) = 1 /jw - e^-jw / jw

b) supposing x1(t) = x(2t)

x1(t) = u(t) - u ( t - 0.5 )

x1(t) = 1 for 0.5

x1(t) = 0 for elsewhere

The blue lake trail is 11 3/8 miles long. Gemma has hiked 2 1/3 miles each hour for 3 hours. How far is she from the end of the

sergeinik [125]

Answer:

$4\frac{3}{8}miles$

Step-by-step explanation:

Given that Gemma has hiked 2 1/3 mile each hour for a total of 3 hours, you can multiply her rate by her time to find the total distance:

d = rt or d = 2 1/3(3)

$2\frac{1}{3}=\frac{7}{3}$

Multiply: $\frac{7}{3}*\frac{3}{1}=7miles$

Now, that the total length of the trail, 11 3/8 miles, and subtract the distance that Gemma has gone already:

11 3/8 - 7 = $4\frac{3}{8}miles$

Solve the given linear Diophantine equation. A) 12x+9y=15 B) 8x+10y=17

Nookie1986 [14]

Answer:

A) (x, y) = (2-3n, 4n-1) . . . . for any integer n

B) no solution

Step-by-step explanation:

A) All coefficients have a common factor of 3, so any solution of the reduced equation will be a solution of the given equation. The reduced equation is ...

4x +3y = 5

A graph of the original shows (x, y) = (2, -1) is a solution. Then other solutions will be those values with a multiple of 4 added to y and the same multiple of 3 subtracted from x:

(x, y) = (2 -3n, 4n -1)

B) The left side of the equation is an even number for any integer values of x and y. The right side is an odd number. There can be no solution.
