2 cards from this section. Quick, good the night before a test.
Define a piecewise function using f(t) = {1, 0 ≤ t ≤ 2}, g(t) = {t, t ≤ 2}. What is the convolution for t=1?
Check the function definitions for limits.
What does g(t) represent in our example?
It increases linearly.
What is the convolution of two functions used for?
Remember the principle of convolution.
For t ≤ 1, what is (f ∗ g)(t)?
Evaluate the integral properly!
Given f(t) = {2, 0 ≤ t ≤ 3} and g(t) = {t, t ≤ 3}, compute (f ∗ g)(t) for t = 2.
Make sure to correctly align the limits according to the piecewise definitions.
Design a piecewise function where f(t) = sin(t) for 0 ≤ t ≤ π; how does this affect convolution with g(t)?
Visualize the changes in the sine function.
