    So the greater the bandwidth the better the controller can track changes und react to them. The time delay between the reference signal and the outputsignal is also increased when the bandwidth is not suitable, right?

  • @infomattersmost
    @infomattersmost Před 3 lety

    Hi Christopher, I am thinking about purchasing some speakers, and they have 3 models that have the same components. The only thing that differs is the Nominal Bandwidth. Here are the 3 Nominal Bandwidths they offer for the same style speakers, just differnt model numbers. 1st) Nominal Bandwidth Horizontal 120° Vertical 60°. 2nd) Horizontal 60°
    Vertical 45°. 4th) Horizontal 90°
    Vertical 60°. I am planing to use the speakers in front of me up high as Nearfield speakers, because when i am mixing i cant here the mix from the main floor speakers. So my question is which one should i pick out of the 3 nominal bandwidths. ? And in laymans terms in a real simple way what is nominal bandwidth, and how could one of the 3 different nominal bandwidths would work for my application , which is using speakers for nearfield speakers only. ?

    @FahadRazaKhan Před 4 lety

    Thank you for these wonderful lecture series, as others have mentioned it is one of the best explanations for the control bandwidth of the system. However, I have a question why do we choose the point -3dB as the bandwidth point, what is the significance of this -3dB point?

  • @justinhendrick3743
    @justinhendrick3743 Před 5 lety +1

    What if the amplitude of the output goes more than 3dB above the DC gain of the system? Is that considered to be "degraded" in terms of system bandwidth?

    • @ChristopherLum
      @ChristopherLum  Před 5 lety +1

      Great question. In general we only look for the minus 3 dB point. However, as the designer, you get to define degraded so if amplification is bad in your application, feel free to use this as your performance metric. However most people define bandwidth as attenuation.

    AE511 The only person who enjoys your control videos more than myself is my wife, who is a pharmacist and does not know control theory! However, video of a dog chasing a laser pointer? She is there for that! Excellent video!
    Quick question - is the "3 dB" Measurement just some arbitrary line draw? Like, why can I not define the bandwidth as 2.9 dB below K?

    • @ChristopherLum
      @ChristopherLum  Před rokem

      Haha, that's great, I'm glad she enjoys them. As you know, there are several other dog examples in my videos. In terms of the 3 dB drop, that is indeed somewhat arbitrary. -3 dB = 20*log10(1/sqrt(2)) so this is roughly when the system attenuates to 0.707 of the original signal. You can chose some other line but -3dB is pretty standard.
