10 Questions
Which equation correctly represents the signal y(n) in terms of x(n) and delta(n-k)?
y(n) = x(n-k)
What is the relationship between the variables n and k in the equation y(n) = x(n) * delta(n-k)?
n and k are directly proportional
What does the symbol delta(n-k) represent in the equation y(n) = x(n) * delta(n-k)?
