2.20 Given the signal $x(t) = u(t+2) + u(t+1) + u(t) - 2u(t-1) - u(t-2)$, find and sketch $y(t) = x(-4t - 1)$.

Step 1
Given the signal 2n - I - n - (n + I + n + 2 + n = x, we need to simplify the expression to find the value of x. 2n - I - n - (n + I + n + 2 + n) = 2n - I - n - n - I - n - 2 - n = 2n - 3n - 2I - 2 So, x = 2n - 3n - 2I - 2. Show more…
