IB Signal and Data Analysis

This course of 7 lectures is given in the Lent term -- as of Lent 2010, the course was taken over by Prof Simon Godsill. The description and notes given here are for the pre-2009-10 course; description and notes for the 2010-11 course can be found here.

Today, signals and data are continuously generated in all walks of life. Here we will address issues of how to understand and analyse such data. In particular we will look at the question of what frequency components are present in the data. Practical methods of extracting such frequencies are introduced: the Fourier transform for continuous signals and the discrete Fourier transform (DFT) for sampled data. The issue of sampling a signal is addressed in some detail, leading to the Nyquist Sampling Theorem for optimal sampling.

Pre 2009-10 course details and handouts are given here

IIB Image Processing and Image Coding

This 16 lecture course is split into two 8 lecture halves: the first half addresses the topic of Image Processing , while the second half addresses Image Coding .

Image Processing: Given the importance of visual images to humans, the range of applications is vast. This course will cover: the basics of 2D Fourier Transforms and the ideas of frequency, amplitude and phase in images; Basic 2D filter design including windowing functions; image deconvolution.

2011-12 Image Processing course details and handouts are given here.

Downloads from the second half of the course, Image Coding, can be found here

IA Exposition

Running for 2 hours each week during the Michaelmas term, Exposition, attempts to improve students' skills in report writing, oral presentations and critical analysis of research/technical information. The overall aim is to improve communication skills .

CUED has an Exposition website which gives information on the structure of the course -- this can be found here
The exact structure of the Exposition course varies according to the selection of students in each group of 12. For example, one key (compulsary) exercise is to write the Report following the Statics Experiment. The timing of this exercise of course depends on when the groups actually complete their statics experiment.
The detailed timetable for JL's 2011 Exposition Group will appear here towards the start of the Michaelmas term 2011.

IB Information Engineering Laboratories

The IB Information Laboratories run in the morning sessions (9.00-11.00 or 11.00-13.00). The exercises build on the work in IA Papers 3 and 4 and illustrate the second year material in Papers 6 and 7. More detailed information on the laboratories, handouts, teaching assistant information etc can be found here.
