Preferred power supply connections?

e14 Contributor

The schematic I am "capturing" are based on public domain circuits for

audio processing modules in a modular analog synthesizer. There are some

standard power connection schemes which I intend to follow consisting of

+/- 15 Vdc and ground. Typically, the +/- supplies go through a ferrite

bead and a couple of filtering capacitors before hitting the PCB's power

nets.

 

What is the best way to make a power net for the PCB components bcause it

is separated from the power input jack by the ferrite bead? If I connect

the connector pins to the supply +15 and -15 nets, I can't use them on the

PCB. So, what is the best net to use to PCB components to the other side of

the ferrite beads? Should use one of the other available supply nets or

make a unique power net?

 

I have played with different ways to do it, and they seem to work, but as

I'm new at this capture stuff, I'd like to know if there are standard or

preferred ways to accomplish this.

 

This image kind of shows what I mean.

 

Thanks

David

    No, it shows a mess.  There is rotated text all over the place, labels

    overlapping other labels and parts, and missing values.  If you don't

    care about your design, there is no reason I should either.

     

     

    Hi Olin, you're reading too much into the "design". This is not a real

    schematic.

     

    I'm only illustrating the power connections. I am showing the +/-15 volts

    to the plug, and one way I was thinking to do the other power nets. I don't

    even know if this design is electrically "real" image

     

    I only ask a little patience. I'm very new to using Eagle and want to learn

    good habits. Would you maybe take a second look? I'd like some advice about

    how to handle the power nets on the "real" circuits I'd like to work on.

     

    Should I do it kind of like in that illustration? Use the supply library

    +/- 15 for the plug and then a generic supply symbol to connect the +/-

    supplies on the components? Or is there a better way?

     

    Thanks for looking Olin.

     

    David

    Olin,

     

    This kind of response is completely inappropriate.  If you don't care then

    don't bother responding.  Why even waste your time?

     

    Unbelievable.
