    Another excellent episode on your electronics journey, Gregory!
    Bob Pease and I both worked at National Semiconductor, many years ago. As you know, Bob was "A Character" as we say in English. One day he and I had a foot race through the Engineering Department in building "C" It was a tie, I think, but a lot of our co-workers were startled and popping their heads up over the cubicle walls! My best memory of the great man!

    Hello Gregory how are you? I would like to ask you a question. If I apply a square wave generated by a function generator to the input of a 31-band equalizer, can I separate them by frequency band? I look forward to your help. I wish you much success always. I'm your fan.!!

      Hi Jose, you could!
      The audio EQ will not roll off fast enough to create a clean sine at the output.
      You probably will be able to change the shape of the square wave enhancing/attenuating the harmonic amplitude.
      Thanks!

      @@AllElectronicsChannel Gregory understood, I have a quality function generator, if I generate a square wave that is formed by an infinity of different frequencies, I will be able to separate them in each frequency band in the equalizer that has 31 bands. This separate signal will go to a vibration table and then excite a 100m/V G accelerometer which will undergo the FFT math treatment. Man, I'm so honored by your great kindness in coming here to help me. Thank you very much!

      @@AllElectronicsChannel you as a great connoisseur of instruments, do you have any references for the 31-band equalizer Behringer FBQ3102HD?

    • @AllElectronicsChannel

      Hi Jose, the square wave is composed of only odd harmonics, with decreasing amplitude.
      You would be in better place with a multi tone signal gen

      @@AllElectronicsChannel If I apply a fundamental frequency of 30 Hz to a square wave, wouldn't the second harmonic of 2 x 30, 4 x 30, 6 x 30... be visible in the equalizer output? I want to analyze these signals after Equalizer in FFT

    Why does the FFT display "baseline" slant and not for example, just straight across the bottom of the scope display?

    • @AllElectronicsChannel
      @AllElectronicsChannel  ปีที่แล้ว

      Because noise is random.. the line would be static with an infinite average.

    Why does the 3rd harmonic have a higher amplitude than the 2nd at 8:51?

    • @AllElectronicsChannel
      @AllElectronicsChannel  หลายเดือนก่อน +1

      That is because the distortion is symmetrical (positive and negative semi-cycles distort similarly). Take a look at this video: th-cam.com/video/acWZLW5EE3U/w-d-xo.html
