SUMMARY

The discussion focuses on computing the energy of three signals represented by the functions tr(0.1t-3), tr(0.2t-3), and p((t-5)/4). The energy of a signal is defined as the integral from negative infinity to positive infinity of the absolute value of the function squared. The participant calculated the energies as 5 for the first function, 2.5 for the second, and 4 for the third function. These calculations are confirmed as correct based on the established definition of signal energy.

PREREQUISITES
  • Understanding of signal processing concepts
  • Familiarity with triangular functions (tr)
  • Knowledge of integration techniques
  • Basic principles of energy computation in signals
NEXT STEPS
  • Study the properties of triangular functions in signal processing

compute the energy?


As far as i know,
i tried to plot the functions and calculate the area under the triangle. but i am not sure that i find the correct answer. Could you let me be sure about the answers?

My answers
1st-->5
2nd-->2.5
3rd-->4
