FOR A SIGNAL V_IN (t) = 10 e^-t u(t) A. WHAT IS THE ENERGY OF THE SIGNAL b. WHAT IS THE ENERGY OF THIS SIGNAL IF PASSED THROUGH A BANDPASS FILTER WITH LOWER AND UPPER CUTOFF FREQUENCIES OF 15 AND 30 hz.

Solution

The average power of signal is defined by; A signal can be categorized into energy signal or power signal: An energy signal has a finite energy, 0 < E < . In other words, energy signals have values only in the limited time duration. For example, a signal having only one square pulse is energy signal.

energy of a signal is 20e^-2t

the energy of the signal decreases when it is passed through when it is passed to lower and upeer cut off frequencies
