plot(abs(fft(vectorname)))

the FFT function returns a complex vector thus when you plot it, you get a complex graph. If you plot the absolute value of the FFT array, you will get the magnitude of the FFT.

How do you modulate in matlab without using matlab tools?

You would have to write your own code for a modulation (Matlab has a convolution function not in the tools), otherwise you can use its built in function in the signal processing toolbox.


How do you convert sequence of images to video in matlab?

You can do this by selecting the sequence of images you want to animate and then using the Matlab's function called "im2frame". This will result in a video.


How do you make graph from an equation in Matlab?

Initially, the equation can be directly realized using Matlab source code. Then various inputs can be applied to it. These values can easily be plotted on a graph using plot or stem command in Matlab.


Convolution in matlab using for loop?

There are a lot of convolution functions in matlab, mostly in the signal processing toolbox, so it depends on what you want to do. Matlab has extensive help files available online.


MATLAB code for FIR filter design in rectangular window using genetic algorithm?

Here is an example MATLAB code for designing an FIR filter with a rectangular window using a genetic algorithm: % Define the desired filter specifications Fs = 1000; % Sampling frequency Fc = 100; % Cutoff frequency N = 51; % Filter order % Define the fitness function for the genetic algorithm fitnessFunc = @(x) designFIR(x, Fs, Fc); % Define the genetic algorithm options options = optimoptions('ga', 'Display', 'iter', 'MaxGenerations', 100); % Run the genetic algorithm to find the optimal filter coefficients [x, fval] = ga(fitnessFunc, N, options); % Design the FIR filter using the obtained coefficients filter = fir1(N-1, x); % Plot the frequency response of the designed filter freqz(filter, 1, 1024, Fs); In the above code, designFIR is a user-defined function that evaluates the fitness of an FIR filter design based on its frequency response. The genetic algorithm is then used to optimize the filter coefficients to meet the desired specifications. Finally, the designed filter is plotted using the freqz function.

How can I programmatically stop a MATLAB script execution using a single command in MATLAB?

To programmatically stop a MATLAB script execution using a single command, you can use the "return" command. This command will immediately exit the current function or script, effectively stopping its execution.


What is the syntax for calculating eigenvalues and eigenvectors in MATLAB in a specific order using the 'eig' function?

To calculate eigenvalues and eigenvectors in MATLAB using the 'eig' function, the syntax is as follows: eigenvectors, eigenvalues eig(matrix) This command will return the eigenvectors and eigenvalues of the input matrix in a specific order.


How can I use MATLAB to calculate and sort eigenvalues efficiently?

To calculate and sort eigenvalues efficiently using MATLAB, you can use the "eig" function to compute the eigenvalues of a matrix. Once you have the eigenvalues, you can use the "sort" function to arrange them in ascending or descending order. This allows you to quickly and accurately determine the eigenvalues of a matrix in MATLAB.


How can I calculate a double integral using the trapz function in MATLAB?

To calculate a double integral using the trapz function in MATLAB, you can first create a grid of points for the two variables you are integrating over. Then, evaluate the function you are integrating at these points to create a matrix of function values. Finally, use the trapz function twice - once along one dimension and then along the other dimension - to compute the double integral.


Is the bandwidth equal in each cycle of a periodic signal?

Yes, If you perform a windowed Fourier Transform of a truly periodic signal using a window function exactly one cycle wide the results will be exactly the same signal frequency spectrum, regardless of where on the signal you placed the window function. But you should also realize the results will also be the same signal frequency spectrum using a window function of any width that is an integer multiple of one cycle (greater than zero), or even without any window function at all. This signal frequency spectrum contains all the information needed to determine what is commonly called the bandwidth of the signal (and that spectrum often contains frequencies outside that bandwidth, but usually only at very low amplitudes so that their loss in filters, etc. is not generally considered significant).


How is interference avoided by using FDM?

How do we measure frequency of guitar in the air?

The frequency of a guitar string vibrating in the air can be measured using a tool called a tuner. Tuners can be electronic devices or apps that listen to the sound of the guitar and display the frequency of the note being played. Alternatively, a guitar's frequency can also be measured using a frequency counter or a spectrum analyzer.


How do you do modulation BPSK with a digital input the modulation must use matlab simulink?

BPSK Modulation can be done by using a multiplier. Digital data must be multiplied with the carrier frequency. In matlab simulink use a multiplier block to one input apply a sinusoidal generator & to the other a Pulse generator
