reading some schematics. One good example are Buchla schematics, which I
find almost impossible to decipher.</SPAN></FONT></DIV>

class=695443605-13052024>When I draw a schematic, I try to have the signals
moving from left to right. I'm also a very systematic person when I do
technical things, so, for example, all of my opamps are drawn with the positive
input pin on the bottom and the inverting input on the top. I draw my
schematics in Multisim, and opamps are always oriented the opposite way in that
program, so I have to go in and flip them all. I space things out in a
very uniform way. Common circuit blocks are always drawn in a similar way
in my schematics. Hence, I can generally tell what's going on at
a glance, even when I haven't looked at a schematic for many
years.</SPAN></FONT></DIV>

class=695443605-13052024>It's the same with PCB layouts -- I can follow the
signals and see what everything is doing very easily, because I lay them out
very systematically.</SPAN></FONT></DIV>

schematics. I also don't like building other people's
PCBs.</SPAN></FONT></DIV><BR>

<DIV style="FONT-FAMILY: monospace,monospace; COLOR: #0b5394; FONT-SIZE: small"
class=gmail_default>I wanted to ask a question that has been on my mind
lately.</DIV>
<DIV style="FONT-FAMILY: monospace,monospace; COLOR: #0b5394; FONT-SIZE: small"
class=gmail_default><BR></DIV>
<DIV style="FONT-FAMILY: monospace,monospace; COLOR: #0b5394; FONT-SIZE: small"
class=gmail_default>I consider myself a beginner in electronics.</DIV>
<DIV style="FONT-FAMILY: monospace,monospace; COLOR: #0b5394; FONT-SIZE: small"
class=gmail_default>I know all the fundamental stuff, or how can I express it...
I understand the landscape of electronics from a high point of view.</DIV>

<DIV style="FONT-FAMILY: monospace,monospace; COLOR: #0b5394; FONT-SIZE: small"
class=gmail_default>However what gets me constantly is this...</DIV>
<DIV style="FONT-FAMILY: monospace,monospace; COLOR: #0b5394; FONT-SIZE: small"
class=gmail_default>When I look at analog electronics schematics, specially big
ones, they don't make sense to me, or at least not within the first few minutes
of looking at them. I find that most schematics are highly "non-linear". By that
I mean that there are feedback loops everywhere, many times from places in the
schematics that are far away from each other.</DIV>
<DIV style="FONT-FAMILY: monospace,monospace; COLOR: #0b5394; FONT-SIZE: small"
class=gmail_default><BR></DIV>
<DIV style="FONT-FAMILY: monospace,monospace; COLOR: #0b5394; FONT-SIZE: small"
class=gmail_default>Schematics that are more linear flowing are easier for
me because I can see the "blocks" and how they connect to each other. But
many schematics are so non-linear and I find that difficult to understand.</DIV>
<DIV style="FONT-FAMILY: monospace,monospace; COLOR: #0b5394; FONT-SIZE: small"
class=gmail_default><BR></DIV>
<DIV style="FONT-FAMILY: monospace,monospace; COLOR: #0b5394; FONT-SIZE: small"
class=gmail_default>How to become better at this? If you are an experienced
electronics engineer, can you yourself understand these "non-linear"
schematics by just looking at them if you have not seen that type of circuit
before?</DIV>
