4. Plotting a Sampled-Signal. Suppose the continuous-time signal x(t) is sampled with a sampling period of o.3 seconds between each sample. Suppose also that the first sample is at t = o and that a total of 12 samples are collected. The table below lists the samples of x(t) that were collected. sample number x(t) 6.0 1 -1.3 -8.0 3 -11.7 4 -11.0 -6.0 6 1.3 7 8.0 8 11.7 11.0 10 6.0 11 -1.3 Using the plot command, make a plot of this signal. The horizontal axis should be labeled: TIME (SECONDS). Make sure that the horizontal time axis shows the correct time for each sample: 0,0.3,0.6,...,3.3.

Please help me answer the question 4 in the image with details on how to do it. Thank you.

Let X be number of gates in an 8-bit adder (i.e., adds two 8-bit numbers) and Y be the number of gates in a 16-bit adder (adds two 16-bit numbers). Which of the following is true of X and Y? A. Y is smaller than X B. Y is about the same as X C. Y is a larger than X, but not twice as large D. Y is about twice as large as X E. Y is much more than twice as large as X
