Summary

1 / 6

Past student reviews · Bernard Lesieutre

Exams were described as fairly straightforward if students completed the review assignment and period exercises. Preparing adequately for class was considered sufficient for success.

What you’ll be able to do

  • Manipulate complex numbers in the context of representing sinusoids

  • Represent periodic continuous-time signals using the Fourier series

  • Represent finite-duration discrete-time signals using the discrete Fourier transform

  • Determine sampling parameters for analog-to-digital conversion of signals

  • Apply digital filters to discrete-time signals

  • Write code using numerical computing software to manipulate signals

About this estimate

The course’s semester-average GPA, not an individual student’s grade. The center uses 5 same-season terms, weighted toward recent results.

The range uses the finite-sample 80th-percentile rank of absolute errors from earlier same-season forecasts. Each forecast uses only records from earlier terms. At least four forecasts are required; bounds are rounded outward and limited to 0–4. This is an empirical estimate: changing instructors or grading policies can reduce its coverage.

8 earlier forecasts · 0.25 GPA average error.

About this comparison

1280 courses over the same term, each with at least 30 recorded letter grades. Cross-listed courses count once. GPA is not a measure of difficulty or teaching quality. The typical course is the median by recorded grade count; tied values are not counted as lower. Grade counts describe course scale, not unique students or typical section size.

Descriptions compare GPA with this group’s average: at least 0.20 higher or lower; otherwise close to average. Section size uses median recorded enrollment: small up to 30, mid-sized 31–99, large 100+. Lectures and discussion/lab sections are described separately.
