Question

The average daily temperature at Washington, D.C. from January 1, 1995, to May 13, 2020. A plot of this temperature data is shown below:

 

**Transcription and Description for Educational Website** --- ### Graph Description The graph represents temperature data over a timeline with days and years marked on the x-axis, ranging from 01/01/09 to 01/01/21. The y-axis indicates temperature in degrees Fahrenheit (F), ranging from 20°F to 100°F. The plot shows a periodic pattern with fluctuations that suggest cyclical temperature changes over time. ### Instructions for Analysis **Objective:** Use MATLAB to compute and plot the frequency content of the temperature data and answer the following questions: 1. **Dominant Peak Identification:** - What dominant peak do you see in the signal's frequency content? (Ignore the peak at zero frequency, which is just the sum of the temperature data.) 2. **Periodicity Analysis:** - What periodicity in time does this frequency peak correspond to? 3. **Sampling Rate:** - What sampling rate (samples per unit time) did you use in your analysis? --- Ensure students utilize MATLAB effectively to analyze the frequency content and extract meaningful insights from the data provided.
