ECE 313/MATH 362
PROBABILITY WITH ENGINEERING APPLICATIONS
Fall 2026
ECE 313 (also cross-listed as MATH 362) is an undergraduate course on probability theory and statistics with applications to engineering problems primarily chosen from the areas of communications, control, signal processing, and computer engineering. Students taking ECE 313 might consider taking ECE 314, Probability Lab, at the same time.
EE and CompE students must complete one of the two courses ECE 313 or Stat 410.
Prerequisite : Math 257 or Math 416
Exam times : See Exam information.
Homeworks : Homeworks will be issued weekly on Fridays and will be due the next Friday at 7pm, through Gradescope (enrollment code 8YGX37). On each homework, we will randomly select about half the problems to be fully graded. Homework assignments and solutions will be posted here. Typesetting with LaTeX is allowed, however, no additional credit will be awarded to typeset homework.
Campuswire: We encourage you to use Campuswire for online discussions related to the class. The course staff will try to answer any question within 48 hours during weekdays. Online questions and emails will not be answered during weekends. Questions during the weekends before exams can be answered during regular office hours. Self-enrollment code for Campuswire is 9067.
Text : ECE 313 Course Notes (hardcopy sold through ECE Stores, pdf file available.)
Office Hour Schedule (TA Office hours start from the third week of the semester)
Before attending office hours, students are strongly encouraged to read the homework problems and lecture material and formulate their questions for the instructors/TAs. This will facilitate a more productive discussion and allow more students to get detailed feedback.
