MASSACHVSETTS INSTITVTE OF TECHNOLOGY Department of Electrical Engineering and Computer Science 6.002 - Electronic Circuits Fall 2000 Homework #8 Handout F00-041 Issued 10/26/2000 - Due 11/3/2000 Readings: Exercise 8.1: Chapter 10, Exercise 10.24, assuming RC time constants are small (on page 575). Problem 8.1: LemE.Tweakit Lem E. Tweakit, a junior in course VI, wants to control his dorm-room lights from his personal computer. He proposes to use a data line from the parallel port on the computer to control the lights, because it is easy to write a program that controls the signal on the parallel port. A TTL parallel port is guaranteed to put out a HIGH signal of greater than V OH = 2.4 Volts and it is guaranteed to put out a LOW signal of less than V OL = 0.4 Volts. However, the lights are 110 Volts at 60 Hz AC, so of course, he cannot directly control the lights from the parallel port. Lem wants to use a relay to work the lights, but the only relay that Lem has in his junkbox is requires 100 mA to reliably close the switch. Unfortunately his parallel port cannot supply anywhere that much current. He decides to use a MOSFET stage to

### 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.
