GUESS THE PERIODIC SIGNAL
1. The function $ x(t)\! $ is an $ odd\! $ function.
2. x(t) is $ real\! $.
2. $ x(t)\! $ has a fundamental period of $ T = 9\! $.
3. The Pk-Pk of the function is 10.
4. The function is offset by a value of +1.
5. Finally, $ a_{0} = 1\! $.
ANSWER
$ x(t) = 5cos(\frac{2\pi}{9}t)+1\! $
