Which equation correctly represents the signal y(n) in terms of x(n) and delta(n-k)?
Which equation correctly represents the signal y(n) in terms of x(n) and delta(n-k)?
- y(n) = delta(k-n)
- y(n) = delta(n-k)
- y(n) = x(k-n)
- y(n) = x(n-k) (correct)
What is the relationship between the variables n and k in the equation y(n) = x(n) * delta(n-k)?
What is the relationship between the variables n and k in the equation y(n) = x(n) * delta(n-k)?
- There is no relationship between n and k
- n and k are inversely proportional
- n and k are equal
- n and k are directly proportional (correct)
What does the symbol delta(n-k) represent in the equation y(n) = x(n) * delta(n-k)?
What does the symbol delta(n-k) represent in the equation y(n) = x(n) * delta(n-k)?
- The ratio of n and k
- The difference between n and k (correct)
- The product of n and k
- The sum of n and k
If x(n) = 0, what is the value of y(n) in the equation y(n) = x(n) * delta(n-k)?
If x(n) = 0, what is the value of y(n) in the equation y(n) = x(n) * delta(n-k)?
