A frequency diagram is a type of graph used to represent a continuous set of grouped data. First, identify the largest frequency. The largest frequency is 12. Therefore, the scale on the vertical ...

A cumulative frequency diagram is drawn by plotting the upper class boundary with the cumulative frequency. The upper class boundaries for this table are 35, 40, 45, 50 and 55.

Thus, in their DSP books you'll see frequency-domain plots like Figure 13 (a) where the frequency-axis is a normalized angle with – f s /2 replaced with –π, and f s /2 replaced with π. The ...
