I want to add the noise filter and also able to display the real time cepstrum for pitch detection using this VI,but I am new to labview and signal processing. I try many filters like the express filter vi , the array based vi and point by point, but all got error and can not use. I also try to use the definition of the cepstrum to convert the FFT specrum to cepstrum but nothing can be seen from it. Can someone give me some hint on how to configure the connection in order to filter noise and display correct cepstrum? Really thanks!
