For the week of November 29, please begin reading Chapter 6 on the Laplace transform. Sections 6.1 and 6.2 describe the forward and inverse Laplace transform operations. Sections 6.3 and 6.4 describe the application of the Laplace transform to solving differential equations and circuits (ZSR and ZIR!). Since you have done this in MATH 212 and ELEC 225-226, we will mention it only briefly in this course. The concept of the transfer function of an LTIC system, H(s), is very important.
If you have notes on the Laplace transform from previous courses (MATH 212 and ELEC 225-226), you might want to find and review those notes. This might make some enjoyable reading over Thanksgiving break.
You are given a data file
sig1.dat
that can be downloaded from the Web version of this assignment at
http://www.eg.bucknell.edu/~kozick/elec32004/hw16.html
The file contains discrete-time data that was obtained by
sampling a continuous-time signal at the rate of
300 samples per second.
The data can be loaded into MATLAB with
the command
load sig1.dat -ascii
after which a variable named sig1 will be available. (The MATLAB command whos gives you a listing of all variables defined in the MATLAB workspace.)
Suppose it is known that either two or four distinct sine waves are present in the data.
Thank you.
