    signal tap quartus II plot and fft

    Today I tried to insert the ADC_DB and DAC_DB vector in simulink. Through Z0H I reconstructed the signal starting from the samples captured by the signal tap. Then I visualized the spectrum The most subdued in blue is ADC_DB At this point I have compared the output of the fir of the FPGA...

    signal tap quartus II plot and fft

    all clear. but for the FPGA I managed to plot the FFT plot. I don't understand how to do it even with the y signal. if i did plot (y) i can't

    signal tap quartus II plot and fft

    I managed to create the filter.. I exported the coefficients, I took the input from the signal tap and only that the plot comes out like this. i did plot (y) how can i fix? i saw that you should do the fft

    signal tap quartus II plot and fft

    I captured the signal from the signal tap. I need to filter the signal tap signal and display it. I have to compare the filter created with ip core FPGA with the one created in matlab

    signal tap quartus II plot and fft

    Hi everyone I'm working with a Quartus II signal tap and I have a problem. Given that I know how to export the data from the signal tap, I need to process them in matlab. I created a signal called ADC_DB and another ADC_DB_filter. These two signals represent a filtered and unfiltered signal by...

    [SOLVED] PINS TERASIC ADDA

    Hello everyone . I am trying to insert the pins into the ADDA terasic board. But I'm having a little trouble. I have currently followed the guide and found a few things. As the example uses channel B, it puts the pin on PLL of JP1. Then on JP5. (in verilog I have a module that deals with the...

    Export from Signal Tap Quartus prime in Matlab

    I Try this: obviously fft () doesn't work. need something else M = dlmread('stp1_auto_signaltap_0.txt', ' ',16, 6) ADC_DA = M(:,1); DAC_DA = M(:,2); DAC_DB = M(:,3); DATA_A = M(:,4); DATA_B = M(:,5);

    Export from Signal Tap Quartus prime in Matlab

    I had already found this thing. I wanted to know if I can modify this code somehow to get the FFTs of the signals that interest me. What should I remove from this listing. The code below comes from a siglnal tap.

    Export from Signal Tap Quartus prime in Matlab

    hi everyone I have to modify this example file which must show me the data of the signal tap. I need to view the FFT of the ADC_DA_F and DAC_DA_F Signal i have to do the same thing for other similar signals, eg ADC_DB, DAC_DB the example file that is generated by the signal tap has the shape I...
