Use the values and write the expression for f(t) as follows:

f(t)={(−24−8t)[u(t+3)−u(t+2)]−8[u(t+2)−u(t+1)]+8t[u(t+1)−u(t−1)]+8[u(t−1)−u(t−2)](24−8t)[u(t−2)−u(t−3)]}

Rearrange the expression as follows:

f(t)={−24u(t+3)−8tu(t+3)+24u(t+2)+8tu(t+2)−8u(t+2)+8u(t+1)+8tu(t+1)−8tu(t−1)+8u(t−1)−8u(t−2)+24u(t−2)−8tu(t−2)−24u(t−3)+8tu(t−3)}={−8(t+3)u(t+3)+8(t+2)u(t+2)+8(t+1)u(t+1)−8(t−1)u(t−1)−8(t−2)u(t−2)+8(t−3)u(t−3)}

Conclusion:

The expression for the given function is {−8(t+3)u(t+3)+8(t+2)u(t+2)+8(t+1)u(t+1)−8(t−1)u(t−1)−8(t−2)u(t−2)+8(t−3)u(t−3)}.

Answer 19

Explanation of Solution

Given data:

Refer to Figure P12.1 (b).in the textbook for the given function.

Calculation:

The function in Figure P12.1 (b) is a piecewise linear function

Write the piecewise-linear definition for the function as follows:

f(t)={0, t≤−3s;−24−8t, −3s≤t≤−2s−8, −2s≤t≤−1s8t, −1s≤t≤1s8, 1s≤t≤2s−8t+24, 2s≤t≤3s0, t≥3s

Form a single continuous definition for the function using step function as follows:

−24−8t, on at t=−3, off at t=−2;−8, on at t=−2, off at t=−1;8t, on at t=−1, off at t=1;8, on at t=1, off at t=2;−8t+24,on at t=2, off at t=3;

Use the values and write the expression for f(t) as follows:

f(t)={(−24−8t)[u(t+3)−u(t+2)]−8[u(t+2)−u(t+1)]+8t[u(t+1)−u(t−1)]+8[u(t−1)−u(t−2)](24−8t)[u(t−2)−u(t−3)]}

Rearrange the expression as follows:

f(t)={−24u(t+3)−8tu(t+3)+24u(t+2)+8tu(t+2)−8u(t+2)+8u(t+1)+8tu(t+1)−8tu(t−1)+8u(t−1)−8u(t−2)+24u(t−2)−8tu(t−2)−24u(t−3)+8tu(t−3)}={−8(t+3)u(t+3)+8(t+2)u(t+2)+8(t+1)u(t+1)−8(t−1)u(t−1)−8(t−2)u(t−2)+8(t−3)u(t−3)}

Conclusion:

The expression for the given function is {−8(t+3)u(t+3)+8(t+2)u(t+2)+8(t+1)u(t+1)−8(t−1)u(t−1)−8(t−2)u(t−2)+8(t−3)u(t−3)}.
