Observed signal Missing Data et's say you're given a signal with some missing data, as shown in the figure above, and your oal is to fill in the blanks. 1. Would you say that this is a supervised learning, or an unsupervised learning problem? 2. Which of the following models do you think fits the data above? o y = A cos(wt + 4) o y = Aj cos(wit + o1) + A2 cos(wat + 2) o y = Ae-kt cos(wt + 4) 3. Describe how you would proceed to solve it if you were given such a problem.

Use of XOR function

XOR function or exclusive OR function was introduced in Excel 2013. This function is available under excel logical functions. For the given statement, the XOR function will return true only when either of the statements is true. It returns false when both the statements are true or when both the statements are false.
