Fourier's results says that a large class of periodic signals can be represented as linear combinations of sinusoids and cosinusoids or, equivalently, complex exponentials. In this lab, we will see this to be true for some periodic signals. Therefore, we will use an approximation given by. What do you observe?
Think about what you have accomplished and how this means that different signals can be written as linear combinations of complex exponentials. What questions come to your mind? Note these questions down so that we can talk about them on Tuesday. Read Section 3. Compare with the analytical expressions you got when working out the homework for parts a and c. The assignment will be due on Tuesday along with the rest of the homework. You may have heard the exciting news that scientists were able to record gravity waves from the collision of two black holes.
What a historic moment for science! In my opinion, it is as much a victory for engineering as it is for science, since the engineering that has gone behind the development of detectors to detect extremely weak signals and the algorithms that are needed to detect the weak signal in the presence of noise are remarkable! One way for people to get a feel for the gravity wave is to convert the gravity wave into a sound signal and such as signal is shown below.
The type of signal recorded is called a chirp signal. A chirp signal is a sinusoidal signal whose frequency linearly increases with time. Express such a signal mathematically. Mathematically, what is the relationship between the two signals? Read about correlation functions.
See Problem 1. The signal actually corresponds to the expansion and shrinking of distances between objects, i.
This should also emphasize the utility of the tools we are learning in this course to model a variety of phenomena from gravity waves to audio signals! Communication systems are often subject to interference from a variety of sources. In this project, you will use MATLAB to read a wav file, simulate the effect of narrowband interference and process the distorted signal to recover the original signal.
You can work in a team of two students. Do a help on these commands or read about them by searching on google.
