Hints
mmm
- 1 Lets say the period is ... 7
- 2 The Average is ... 4
- 3 The Minimum Value is ... 1
- 4 The signal is ... real and odd
Answer
Now that I have selected random properties lets see if an answer can be formulated...
- Since it is real and odd the base signal is a $ \cos $
- Since the period is 7 ... $ w = \frac{2\pi}{7} $
- Now use the hints of Minimum of 1 and the Average of 4 the signal can come together as...
$ 3\cos(\frac{2\pi}{7}t) + 3 $
