A coaxial cable (RG59 75Ω) has a maximum voltage standing wave of 57 V and a minimum voltage of 12 V. The transmission source provides a signal with a voltage of 15 V and a current of 2 A. Determine: a) the reflection coefficient, b) the standing wave ration, c) the value of a resistive load, and d) the output power.

Devoting time to a journal can help you become a more effective, practiced writer. It allows you to explore your thoughts, experiment with prewriting techniques, or save and share important ideas. Complete a journal entry that describes how your journal portfolio this semester has assisted you in your own writing process. If you feel it hasn’t been as effective for you, please share your thoughts on that.

Suppose that daily temperature has a roughly linear relationship with humidity, cloud cover, and historical temperature. We have the following two data points, each describing a different day: Humidity Cloud Cover Hist. Temp Today Temp 10 50 60 60.25 16 20 62 63.3 In the second part of this problem, you will formulate a linear program to determine the best weights , , and to use to predict today’s temperature from the features humidity, cloud cover, and historical temperature. In this problem, the best weights are those that minimize the total absolute prediction error.
