Phase function is tan-1(cosnθ/sinnθ)=tan-1(tan nθ)=nθ 4. The signal given by the equation is known as:
A. Energy signal
B. Power signal
C. Work done signal
D. None of the mentioned
Answer:A

Explanation: We have used the magnitude-squared values of x(n), so that our definition applies to complex-valued as well as real-valued signals. If the energy of the signal is finite i.e., 0<E<∞ then the given signal is known as Energy signal.
