## convolution of $e^{-t}$ and 1-t

I cannot solve the convolution based on $h= e^{-t}$ for $tge0$ and $u(t) = 1-t$ when $0 le t le1$.Every time I try...

## Rotor speed of separately ecxited DC motor with terminal voltage and field current

How does rotor speed vary with terminal voltage and field current of a separately excited DC motor? Is it different for a no load condition vs other loading condition?...

## Unused output of LTC6957-4 (or LTC6957-3)

The LTC6957-4 has two complementary CMOS outputs, and I only need one. What do I do with the unused output? My goal is to minimize noise on...
