Assignments

Assignement problems (from section B of the textbook) will be posted here.

Completed assignments should be submitted using UVic's Brightspace site by 6pm the date they are due.
Watch an example of assignment submission.

Solutions to the assignments will be posted here.

Assignment #1 (Due Saturday, Jan 18)

Problem: Consider the unity negative feedback system with G(s)=20*K/[s(s+1)(s+20)].
1. Sketch the root locus.
2. Find Kv.
3. Sketch Bode and Nyquist plots.
4. Find K so that zeta=sqrt(2)/2 for the closed loop system.
5. Find phase and gain margins for this K.
6. Sketch the step and ramp responces of the closed loop system for this K.
7. Discuss the connection between Kv, zeta, margins and the responce of the closed loop system.

Assignment #3 (Due Sunday, February 2) :

Problem 1: Sample the two signals x1(t)=sin(2*pi*3*t) and x2(t)=sin(2*pi*0.3*t) with sampling period T=0.2.
Sketch the spectrum of the continuous signal, the spectrum of the sampled one and the reconstructed signal obtained by ideal lowpass filtering of the sampled signal. Confirm your results with Matlab. For a .m file, Click here.

Questions B-3-4, B-3-6, B-3-7, B-3-15, B-3-19 from the textbook.
