Play with the convolution applets provided
on the website (http://eeweb.poly.edu/~yao/EE105, click on 'demonstrations'
Problems (in the texbook)
Prob. 2.8
Prob. 2.11 Hint: du(t)/dt=delta(t)

Announcement:
There will be no class
on next Monday (2/19). We will have the first Midterm Exam on 2/20 at the
recitation hour, 12:00-12:50PM, RH115B. The materials to be covered include:
Concept of continuous and discrete time signals,
simple operations on these signals (translation, scaling, reverse, etc.)
Concept of continuous and discrete time systems
and their properties (linearity, time-invariance, causality, stability,
memoryless)
Properties of linear, time invariant systems
and their characterization by impulse response
Calculation of convolution sum and convolution
integral
Representation of LTI systems by differential/difference
equations: concept of initial rest condition, solving differential equation
by recursion.
