Solution
The correct option is D 7
Energy of signal x(n) = Energy is even part of signal x(n) + Energy in odd part of signal x(n)
= 3 + 4 (Energy and power are additive in nature)
= 7
Energy of signal x(n) = Energy is even part of signal x(n) + Energy in odd part of signal x(n)
= 3 + 4 (Energy and power are additive in nature)
= 7
