  1. Course Title:Communications II
  2. Pre-requisite:ELHT 413
  3. Co-requisite:ELHT 441L
  4. Credit:3
  5. Course Description:This course includes a review of random variables, bit error rate and matched filter concepts. It involves the study of pulse communications (PAM, PWM, PPM and PCM) and digital modulation techniques (ASK, FSK, PSK systems). It covers the study of signal space concepts, generalized orthonormal signals, information measures such as entropy, channel capacity concept, efficient encoding, error correcting codes and information theory, data compression. It also includes the study of Time Division Multiplexing.
  6. Course Objectives and Relationship to Program Educational Objectives:

After completing the course, the student is expected to understand the concepts and analysis of digital communications systems. It involves the goal of providing the student with technical skills to predict the performance of simple digital communication systems. Also, the course hopes to develop deep appreciation of the importance of this knowledge as applied in actual industry or professional work. (1, 2, 3, 4)

General Class Policies

  1. No make up quizzes, final examination, pre–test or seatwork will be given. A score of seventy percent of your highest quiz will be given for a missed quiz. However, if there are two or more quizzes that were missed, a score of zero will be specified for those quizzes. Student Portfolios shall be checked at the end of the term, bring all returned quizzes, homework, seatwork, pretests. Missing quizzes, homework, seatwork, or pretests will mean a grade of zero.
  2. Cheating of any form will immediately result to a failing grade.
  3. Student Recitation and board works will be given appropriate additional credit. Pre– tests are also additional credit without any divisor; however, check up quizzes are not.
  4. Passing. Passing for this class is 60%.
  5. Examinations. All multiple choice questions in any examination are right-minus-wrong. Quiz booklets must be submitted one meeting before the scheduled exam. No quiz booklet, no exam.
  6. All lectures and class records may be seen and downloaded at: Contents of the site are constantly revised. Wait for announcements before any resource may be downloaded. To download, right – click the link then choose Save As. Lecture handouts are not a requirement during class discussions.
  7. Intelligent Noise is permitted, as long as it will not interrupt the class discussion.
  8. Avoid coming late to class. An attendance sheet will be passed around at the beginning of the class.
  9. Absences. A total of 6 absences (equivalent to 9 hours) would mean failure of the course due to absences.
  10. No grade of 7 (Incomplete) will be given to any student of this lecture course.
  11. Consultation Hours: WF, 1:30pm to 3:00 pm; MWF 4:30pm to 6pm. Please make an appointment at least a day before for any consultation. Consultation regarding the course topics are very much welcome.
