x(-t-2) has been time reversed so the opposite applies. It is best to think of these by drawing out simple arbitrary signal (like a pulse or step function) and remember that x(-t) is just reflecting it around the y-axis (think of the function as a rigid frame that can be rotated at the y-axis).

Any ideas?

Hello, I am an undergraduate student and I am doing some data/signal analysis using the Time Frequency Toolbox for MATLAB (http://tftb.nongnu.org/). Specifically, I am using the Wigner-Ville Distribution (henceforth known as "WVD," as implemented in the tfrwv.m function in TFTB). Basically...

hmmm ... right you are ... I wonder why i didnt catch that. I did not consider that this was without replacement. Cool Thanks a lot dude.

Homework Statement Some Transistors of two different kinds (say N and P) are stored in two boxes. You know that there are 6 N's in one box and that 2 N's and 3 P's got mixed in the other box, but you do not know which box is which. You select a box and a transistor from it at random and find...
