    Balancing act RLC circuit

    ok that is what I did last time I think you got confused because bothe the power is 20 watts and the resistor is 20ohm so the result is 151!

    I'm going to let it run its course back tomorrow!

    simulating this looks good! so now will this pre-amp and amp be good for all the frequency filter I will simulate one in the middle of 45Hz and 7000Hz and see what it's saying thank you very muchly

    which parameters? I see R13 and R23 are changed

    Sorry my mistake the two audio files are different for the 45Hz and 7000Hz, they are not related in any way!

    It's not even dipping look at the time on the 45Hz and when the peaks and troughs there are no troughs on the 7000Hz analysis

    No but the highest peak now reaches 9 volt instead of the prefered 8.4 so it has adjusted it slightly, I think we're getting somewhere! I don't know if this helps but I want to remind you that the circuit worked as desired when R13 was 4.7k and R23 was set to 1k but thats not acceptable because...

    did you run the sim I uploaded the sound file in the form of .txt and the .asc file for the 7000Hz

    nope not yet still tops out I hope you have not exhausted your ideas:) thanks again for helping this is the last part if we get this running for the lowest frequency and the highest frequency then the middle frequencies should work.

    What will higher throughput do and how does it help with the 7000Hz filter? thanks, it hasn't seemed to have done anything noticable!

    complete circuits yes changed the resistor R20 and R21!! 7000Hz 45Hz

    this shows the place where I put the, out of the filters this shows the ammended resistors

    nope it's not having it, still topping out!!

    Running sims now.

    what do you mean by in series with (R13 and 22uF, C14)

    Balancing act RLC circuit

    I read the manual! I still do not know how to set a 20watt load though, any suggestions?
  17. Maglatron

    the 45Hz one out of the sig gen is at the top 46millivolt the 7000Hz one out of it's sig gen it 76millivolt And I think this is the culprit
  18. Maglatron

    Sallen Key Low Pass Filter, bandpass filter

    this is puzzling because they both cap out at 800millivolts
  19. Maglatron

    Sallen Key Low Pass Filter, bandpass filter

    They both centre about 0volts the signals are from the signal generators and are in green!!

    Sallen Key Low Pass Filter, bandpass filter

    so I have not tried changing the R13 or cap C14 yet any suggestions as to what I should set these at to change the outcome, I tried 1uf and 2200uf and there is no major difference to be honest
