Question 1. Consider the signal below on the left. 1) Write
... 2) On the axes to the right, plot the frequency domain representation of the signal. (Make sure to label axes and relevant values.) Question 2. Circle all of the following which are advantages of using modulation. (Could be more than one answer.) (i) Systems can have smaller antennas due to higher c ...

An algorithm predicts the next sample based on the previous samples, and the encoder stores only the difference between this prediction and the actual value. If the prediction is reasonable, fewer bits can be used to represent the same information. For au ...
