Homework Statement
Firstly, I'm sorry for my bad English - I'm from Bosnia and Herzegovina.
I need help in determining type of two discrete signals. Here are problems:
1)
2)
I have tried, and I posted below where I stopped and what's confusing me.
Homework Equations
The Attempt at a Solution
1)
I got energy 9/8, using following equation:
But when I'm trying to calculate power, I'm confused and I don't know how to solve it because then I have sum going from 0 to N (not to infinity). Can you please help me with this and explain how it goes.
2)
I got inifinity energy because I have sum from 0 to infinity of 1/n, and when n=0, 1/0 is infinity, and that's it. Am I right?
But again I have problems with finding power. I got this, and I have no idea what now:
I'm asking you for instructions, not solving problems and results - that woulnd't help me if I don't understand how to solve it and how did you get the result.
Thank you in advance
