    any idea's

    Sallen Key Low Pass Filter, bandpass filter

    actually much much better just need a tiny bit more, needs to come down about another half volt but on the other hand it is NOT clipping so this is goood, no I take that back that was before the filter after the filter there is still massive gain just to clarify this is the setup for all af the...

    Running simulations now! 7000Hz dead slow so I'll be a minute:)

    what and then run both the 45Hz and 7000Hz and look at them?

    Sallen Key Low Pass Filter, bandpass filter

    So I'm looking at it but not sure what I'm looking at I'll open the 45Hz version like you said and do I raise them in stages of 5 do these two caps C15 C17 have to be equal??

    wait a minute if I'm not supposed to be changing the R23 resistor because its before the amp and I'm only making one of those but then when run with the 165k the 7000Hz tops out at 10.5V!

    Sallen Key Low Pass Filter, bandpass filter

    Can I use the same model of the envelope detector, ie, the BAT43 and the 100nF cap and the 1Meg resistor, (just checked 7000Hz and it works like a dream, so I'm nearly done here and I shall build it; just simulated the highest frequency and changed the variable resistor R23 to 1k also, I'm not...

    Balancing act RLC circuit

    ok sorry dood! I'll give it a good read!

    Sallen Key Low Pass Filter, bandpass filter

    planning on building it soon, just waiting on a couple more bits and pieces, trying to cover absolutly everything that I can without actually building, the parts may arrive before the 20th but it's christmas so i'm expecting after christmas maybe early jan got the bar graph LED's the LM314's the...

    Sallen Key Low Pass Filter, bandpass filter

    because I wanted to play a tune and see the filters working with the music, it isn't nessessary just though it would be cool!

    yeah I have a ryzen 5 5000 series with 48GB of ram, Ive been told that AMD is no good what do you guys think?

    Balancing act RLC circuit

    ok please can you tell me how to label the nodes, I've been wodering this for some time, thanks! and also how do I set a 20watt load in LTSpice, it's ok guys I got it a bit, BUT I don't know how to label the current and power

    the sim box is going ultra slow but it's not dropping out I dont think I will be able to put all the filters in one schematic to be honest I recon I need a faster pc laptop!

    ok yes I see what you mean!! thank you!

    Balancing act RLC circuit

    so this is the voltage power and current graph with a 20watt load resistor but when I click current of the 20ohm resistor it shifts the voltage on the 20watt load to a corrosponding approximate 8volts when it should still be at around 50

    it's for another project posted in the wrong thread any wa R=v^2/P so for 20watts load with voltage at 52v the resistor equals 135 I'm going over to the other thread now!

    How do I make a 20watt load in spice??

    Sallen Key Low Pass Filter, bandpass filter

    so I built the second filter and its perfect it filters out the 45Hz and does not let 45Hz pass through!

    I dont have BAT43 in my library, so I've used a BAT46 the results are good!!
