Energy vs Power Signals, Z-Transform and LTI Systems Explained
Energy Signals and Power Signals
Q1. Differentiate between energy signals and power signals. Can a signal be both? Find the energy of x(t) = e⁻²ᵗu(t). (5 marks)
Energy of a signal: E = ∫|x(t)|² dt over (−∞, ∞). For a discrete signal, E = Σ|x(n)|² over all n. Average power: P = lim (T→∞) (1/2T) ∫|x(t)|² dt over (−T, T).
Difference:
- Energy signal: 0 < E < ∞ and P = 0. It is finite in duration or decaying. Examples: rectangular pulse, e⁻ᵃᵗu(t) for a > 0.
- Power signal:

Expert Testimony Standards
- Daubert v. Merrell Dow Pharmaceuticals, Inc. (1993): Replaced the Frye general acceptance test. It establishes the trial judge as the “gatekeeper” who must ensure all scientific expert testimony is both relevant and reliable to exclude “junk science”.
- Kumho Tire Co. v. Carmichael (1999): Extended the judge’s gatekeeping obligation and Daubert‘s reliability requirements to all expert testimony, including technical and other specialized non-scientific knowledge.
