2 cards from this section. Quick, good the night before a test.
Calculate (f ∗ g)[0] if f[n] = {2, 0} and g[n] = {1, 1}.
Look at the first elements of both sequences.
What is the value of (f ∗ g)[1] if f[n] = {1, 2} and g[n] = {1, 1}?
Sum the products of overlapping indices.
What is the convolution of f[n] = {1, 2, 1} and g[n] = {1, 1} at n=0?
Check the first elements of both sequences.
True or False: The result of (f ∗ g)[0] will always equal f[0]*g[0] in discrete convolution.
Remember the basic definition of convolution at the start.
Given f[n] = {2, 1} and g[n] = {1, 3}, find (f ∗ g)[n] for all indices.
Add contributions for each n index.
In a digital system, how does the outcome of (f ∗ g)[2] change if g[n] has a delay? Provide a scenario.
Think about how delays affect signal timing.
