The following questions must be answered correctly!

1. What is the condition necessary for x(t+mT) to be equal to x(t)?

2. Periods T1 and T2 are fundamentals in x1(t) and x2(t) , determine for the equation x(t)=x1(t)+x2(t) a rotational no. that will make it periodic.

3. Determine the period ofx(t)=x1(t)+x2(t)T1 and T2 are fundamental periods of x1(t) and x2(t).

4. When can we term x(t) or x(n) as energy signals?

5. Given cos2t+sin3t, determine the period.

6. Time in speech signal, ECG and EEG is a common independent variable. True or false?

7. What is the property exhibited in y(t)=x(1-t)?

8. Determine the value of x(n) given that x(2n) is (0,2,3,0,0,0,0,0).

9. Given that x(n)=(0,0,1,2,3,4,0,0), determine the value of x(n-2).

10. A signal x(t) is said to be non- linear when?
