Introduction
The objective of this lab is to use computers to analyze the spectra of real-world signals. The Discrete Fourier Transform (DFT), which is the discrete-time version of the Fourier series, is the main tool we will be using. Once a signal is sampled, the spectrum can be analyzed by applying the DFT to the samples. The DFT can be rapidly computed using an algorithm known as the Fast Fourier Transform (FFT). Mat lab has a built-in function, FFT, that implements this algorithm. The FFT algorithm was discovered by Gauss and later rediscovered and popularized by Cooley and Tukey in the late 1960's. The ability to perform spectrum analysis on a computer revolutionized science and engineering, and the FFT is one of the most important tools in signal processing and computational science. In fact, you have all encountered the FFT before; every time you listen to an MP3 file or view a JPEG image you are using an FFT-based algorithm.
What is the frequency of the sinusoid that was sampled? Was it adequately sampled, at or above the Nyquist rate?
How many samples were acquired per cycle of the sinusoid?
Lab Exercise
Mathematically explain why the spectrum of the 150Hz sinusoid in the warm-up did not consist of two perfect peaks. This effect is often called "spectral leakage".
Find the spherical coordinates for point P and find an equation for the surface of the sphere.
All three cycles started at zero when you were born. How long does it take until all three simultaneously return to that initial condition? How old were you, or will you be, on that date? Plot your biorhythm near that date. You should ?nd the lcm ..
Simulate 2000 coin flip experiments with a biased coin with "success" probability (chance of 1) p = 1=5. Plot an outcome of the proportion of successes with respect to the number of coin flips. Supply your code.
Write a program that, given a list of 5 social security numbers, finds the memory locations assigned by the hashing function h(k) = k mod 55 to store customer records. program should be able to handle collisions.
Write a matlab function to perform gauss-jordan elimination with pivoting. Modify the pivoting so that it is using the row with the highest absolute value rather than the first non-zero row.
Write a program to calculate the characteristic impedance of all the transmission line topologies
Write a MATLAB function that takes a matrix, a row number and a column number. Beginning with the row number passed to the function, scan down the column passed to the function and return the row number that contains the largest absolute value in ..
Prepare a program in Matlab to add two numbers from two arrays using try catch construct. Initialize two arrays of different size, and then prompt the user to input indexes for each of the two arrays
Write down your threshold amplitude and duration values in a table and enter into an mfile. Plot the current versus duration. This is called strength-duration curve.
Compare your filter with that given by the Matlab function ‘bilinear' for the same conditions. Manually design a second order digital filter, with the damping ratio given in the table.
Design a normalized lowpass analog filter by using one of Matlab's routines: buttap, cheb1ap, cheb2ap, ellipap to get your analog poles
1.) Write a MATLAB m-script that will generate a damped sinusoid (frequency = 440 Hz) with a time constant of 0.25 sec. Set the time axis for 0 to 6 time constants.
