Schematics & standards
Using a rectangle for a resistor allows the value to be inserted in it -
quite useful where they're close. And therefore 4K7 takes up less room than 4.7K - and a full stop is more easily missed when reading. Similarly a circle for an electrolytic, oval for non electrolytic. After all, an IC is just a box - not a representative of what it does. As regards a dot where two cables join, I agree. For some reason this isn't used much these days. With usually a gap where two circuits cross rather than a loop. With a dot you don't have to do either. -- *I used to have an open mind but my brains kept falling out * Dave Plowman London SW To e-mail, change noise into sound. |
