comment Simple proof for a continuous-time linear system and impulse $\delta$?
Apparently the only way is to break up into piecewise impulses as usual. So this question is answered for me.

comment Basic measure theory question, if there exists a set such that $\mu(E)<\infty$ then $\mu(\emptyset)=0$ - answer check
What do you mean by $E$ in $R$, do you mean open set $E$ in a topology on $R$?

comment What is a bit-shifting standard C function for calculating $f(x) = \frac{(2^{16}- 1)}{(2^{32} - 1)}\cdot x$
I'm writing a driver for the PIC32MX family, and I'm allowed to use specific bit lengths. Also, I just resorted to the division operator, but I learned a lot making this post. And if it should not work right, I'll come back and refer to these answers. Not only am I allowed, but I have to know the size of my types, I'm writing a freakin driver for and only for a family of 32-bit MCUs!

I don't think any of the above comments are correct. Making answer now...

@Oleg567 that's casting, not scaling

@AndréNicolas thanks. Where did you read that? And is it an iff condition?
