Dear all,
I think a half-high (centered) dot "·" is a better (and more standard)
multiplication sign, it does not take much space and it cannot be
confused with the decimal separator ".", for instance
1 + Ts·s - A·s^2
1 + 2.·s - 0.27·s^2
However, I think the decimal dot shouldn't be used in a block diagram,
its only use is to indicate they are real numbers, but block diagrams
never refer to integers so the decimal dot is somewhat pedantic.
?
When a decimal number is integer, the dot is not displayed. With your
dot, it would give
1 + 2·s - 0.27·s^2
So the confusion could be only with cases like 1 + 2.55.s
I was told that in formulae, the most standard is to use space between
multiplied symbols.
This is what looks the most widely used. Please see for example
https://en.wikipedia.org/wiki/Autocorrelation or any other page using a
lot of maths.
Output with \cdot :
vs wider space
or still wider:
