Is exponential function energy or power signal?

it is like a capacitor discharging and giving power to the mobile phone to function. the output voltage of the capacitor is given by a decaying exponential. hence, it is an energy signal.

How do you know if a signal is energy or power signal?

If x(t) has 0 < E < ∞ and P = 0 , then it is a energy signal, where E is the energy and P is the average power of signal x(t). The signal which has finite average power and infinite energy is called as power signal.

Is exponential signal an energy signal?

"A signal that decays exponentially has finite energy, so, it is also an energy signal."

What is energy signal and power signals?

A power signal has infinite energy and an energy signal has zero average power. Transient (finite duration) signals are energy signals while periodic signals are power signals.
