Tutorial: Group delay
 
07:34
Learn how to calculate the group delay of a discrete-time system (includes examples). NOTE: Group delay is more precisely defined in terms of the *argument* (abbreviated "arg") of the complex exponential, i.e., group delay is the negative derivative of "arg(H(e^jω)." Consequently when you write H(e^jω) in the form A(e^jω)e^j(arg), the "A" (amplitude) function can go negative (adding a step discontinuity of plus/minus pi to the phase), but the "arg" function is independent of this discontinuity. At 3:23 -5ω should be identified as "arg(H(e^jω)" (similarly for -2ω at 6:15). ** See the full collection of problems and tutorials at http://www.rose-hulman.edu/~doering/ece380_tutorials_and_problems.pdf **

CORRECTION: At 2:50, the graph heading on the right-hand stem plot should add "x[5]h[n-5]" ("h" instead of "delta"). ** See the full collection of problems and tutorials at http://www.rose-hulman.edu/~doering/ece380_tutorials_and_problems.pdf **

MA 381: Section 6.3: Law of the Unconscious Statistician
 
04:16
Discussion of the meaning of the Law of the Unconscious Statistician. There are sample problems, but I did not prove this law in this video. The Law of the Unconscious Statistician gives us a "nice" formula for computing the expected value of a function of a given random variable. For example, if X is a random variable, then the law gives us a nice way to compute E(h(X)), where h(X) is a function of X, such as X^2.
