ELEC 2120 Su 2013 Roppel Homework 1 Assigned Fri. May 17 Due Wed. May 22 at the start of class. Instructions: Questions 1 – 10 are not for submission. Solutions will be provided on the due date. Question 11 (only) should be submitted in class on the due date. Questions from Section 1.1 1. (a) The voltage from a certain sensor is v(t). Does this meet the definition of a signal? Why or why not? (b) The pose of a mobile robot is defined as p(t) = [ x(t), y(t), θ(t) ] where x(t) is the x coordinate of the center of the robot, y(t) is the y coordinate of the center of the robot, and θ(t) is the heading angle. Does p(t) meet the definition of a signal? Why or why not? (a) Yes, since v(t) is a real-valued function of the time variable t. (b) Not according to the textbook definition, because p refers to an array of values rather than to a single value. However, in a practical application we may choose to understand p(t) as a set of related signals and process the data accordingly if it is reasonable to do so.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
