Tell us about yourself!
MattB34, thanks for your answer.However you link seems to be broken I cannot reach the paper. If you could send it again it would really help me.As a matter of fact, i'm trying to build my own noise cancelling circuit as part of a project for my competitive exams at the end of the year. As a consequence, I am interesting in understanding the maths behind this circuit (even if it means heavy tranfer functions). It would allow me to have a basis of comparison for my circuit.I've already put a lot of work in establishing the equations behind the circuit, and I would like to understand how the phase shift works.Thanks for your answers anyway ! :)
Here is the phase change i've found. The phase change without taking into account the distance between the microphone and the speakers inside the headset is in blue. In magenta this distance has been taken into account. Anyway, the phase changes and does not stay at +/- π... If someone has figured it out and can help me ^^Thanks !
Great work here ! Thanks !I'm trying to understand how the system works. I've drawn the Bode Diagrams of each part of the circuit, but the phase change never reaches π either -π... Could someone help me to understand how it works please ?Thanks ! :)
