Problems 1.4-1, 1.4-4, 1.4-5, 1.4-7, 1.7-1, 1.7-2.** You can redo Problems 1.7-1 and 1.7-2 and submit your solutions on Monday. **
The URL http://www.jhu.edu/~signals/ contains several interesting Java applets that illustrate signals and systems concepts. Please visit this web page, and check out the System Properties link. Focus on the Continuous-time systems for now. The objective is to classify whether systems are linear, time-invariant, causal, etc. by applying various input signals and observing the system output signals.
Try as many of the systems as you would like. At minimum, classify systems A and F, and submit your solution on Monday, September 20. Do not worry about classifying the systems as stable, since we have not discussed stability. Make a note if you discover any interesting systems other than A and F, so we can look at them in class.
The experiments will work fine if you apply only one input signal at a time. Some useful signals to apply might be a unit step u(t), a delayed step u(t-1), a scaled step 2*u(t), and a sine wave sin(t). You can try others also, but these should get you started.
