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 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
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

I'm in my 4th year in Electrical Engineering. Thankyou so much sir for this splendid video.
You are most welcome!
Would love to explore what is giving extra THD in the circuit
I love the new format.
🙏🏼🙏🏼🙏🏼
You are the best of all electronic. Brazuca representando.
Hahahaha thanks Leandro!!
Nice oscilloscope! Rohde and Schwarz.
Well done

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

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

What Arduino simulator is this??? I'd love to know it looks the bomb I want it
Arduino simulator ?
What is a sirqkwit
😏😏
Dead bug mounting!! hahahaha.
Good
