Question

Hello. I believe I have the answer for the second part. I'm just confused on the first part finding the energy, and the last part determining wether the equation is an energy signal or power. 

**Title: Understanding Signal Energy and Power** **Find the Energy of a Signal** We are tasked with finding the energy of the signal \( x(t) = 2te^{-\frac{t}{2}} p\left(\frac{t+1}{3}\right) \), where \( p(t) \) is defined as a pulse function. **Graph Description** The graph displayed shows the pulse function \( p(t) \). It is a rectangular pulse centered around \( t = 0 \), with values: - \( p(t) = 1 \) for \( -2 \leq t \leq 2 \) - \( p(t) = 0 \) otherwise The x-axis represents time \( t \) ranging from \(-5\) to \(5\), and the y-axis represents the amplitude \( p(t) \). **Find the Average Power of a Signal** Next, we need to determine the average power of the signal \( x(t) = 5e^{-j\frac{t}{5}} \). **Energy vs. Power Signal Inquiry** The final task is to assess whether the signal \( x(t) = 3e^{-j\left(\frac{3\pi}{2}t - \frac{\pi}{2}\right)}u(t) \) is an energy signal or a power signal. We need to determine the nature of this signal and provide reasoning. --- In this exploration, understanding the characteristics of energy and power in signals is essential. Energy signals have finite energy and zero average power, while power signals have finite power and infinite energy over infinite time.
