Calculate the function x1[n] and x2[n]

 

I. OBJECTIVES Graph signals and calculate either the energy or power of the signals. II. EQUIPMENT AND MATERIALS Computer with MATLAB III. INTRODUCTION The terms signal energy and signal power are used to characterize signals. The signal energy of a signal x[n] is defined as For the signals have infinite energies, the average signal power is used. For periodic signals, the average signal power of signal x[n] is defined as IV. PROCEDURE E. E = | x[n]|2 - | x[n]| N Given two signals: x1 [n] =ramp[n-2]-ramp[n-6] x2[n] = 3 cos (zn) + 2 os (n/2) P = Have the instructor check and sign off after finishing each step. Drop the signed paper in Blackboard before 2:30 pm next Tuesday. Useful hint: Instead of typing each statement in the MATLAB Commend Window, you can open a new script and use the editor to type the statements, and then save the script as .m file. K 1. Calculate the signal energy for x1[n] (0 < n 10) and signal power for x2[n] (find the fundamental period N first) by hand:
