    Thread Summary
    
                The user is experiencing issues with a real-time display graph showing spikes instead of a 500 Hz sine wave. The final answer suggests using a physical oscilloscope or a sound editor like Audacity to view high-frequency waveforms, as the real-time display is limited to a few tens of Hz. An equivalent-time sampling technique at 498 Hz can also be used to visualize the 500 Hz sine wave. For saving the signal to a PC, optical S/PDIF is recommended as the simplest method, or the analog output can be used if additional DAC and ADC in the signal chain are acceptable.

    Hi,
    
 
    I am using real time display graph to plot sine tone freq=500hz. but I am not getting the correct output in real time display graph? I am getting spikes instead of sine wave. I just want to know what are the proper setting for realtimedisplay block. The pic of project is attached
    
 
    Thanks

      The simplest way to do it is optical S/PDIF, assuming you have a sound card that can support it. That way, you'll get a direct representation of the audio signal recorded on your computer.
      
 
      You can also take the direct analog output from the board into the computer, but that of course has the problem of adding an additional DAC and ADC to the signal chain, which means that you're not truly getting the same signal as what's in the DSP.
      
 
      However, depending on the level of detail you need in this application, the analog approach might be good enough!
