Question

Simulink model for DC shunt motor does not give correct output despite no errors.
The attached Simulink .mdl file (MATLAB 2017) contains a model for DC shunt motor. The DC motor block was cut and pasted from MA...

Question

How do we make sure that the magnitude response of W(e^jw) is being calculated at the same set of frequencies in W’ by the command 'freqz' at every iteration?
For the equation in the attached file, FB(e^jw) is the Fourier transform of the feedback filter fb and W(e^jw) is the Fourier...

Question

how can i integrate an array with respect to frequency w (omega)? the command "integral" requires function 'fun' to be declared as function of omega. how can i do this?
FB and W are frequency responses of two FIR filters fb and w. This is essentially what I am doing: numer1=(abs(FBW-W)).^2; f...

Question

i have declared an FIR filter as fb as given below. Now, i want to find its Fourier transform as FB(jw) with respect to frequency w (omega). How can i do that? I dont think its the same as taking DFT.
fb=fir1(50,[0.2500 0.8750]); %FIR filter fb

Question

Hi. I am trying to create a loop for adaptive feedback cancellation. While the code runs without an error, i am not getting any output. Can anyone please help correct my mistake? Thank you in advance :)
[x,f,nbit]=wavread('tapestry.wav'); fb=zeros(length(x),1); %feedback signal, output of original...
