Compare the results for n=4 and n=8arrow_forwardCan you check if my step is correct?arrow_forwardI need help explaining on this example on how can I define the Time-Domain Function, Apply the Laplace Transformation Formula, and Simplify to Find the Frequency-Domain Expression. I need to understand on finding Y(s)arrow_forward
