I'm learning the fourier transform but I'm confused by a problem.
As an exercise, I've created a Python program to model the effect of a
low pass RC filter on a digital waveform. The prog creates...

I was at the appliance repair shop the other day
and saw heaps of repair orders piled on the front
counter--electronic motherboards of various kinds.
I asked the tech what usually failed. I expec...
Please refer to Fig 5,Pg 2, TI datasheet LM431.
What i need is a 2-terminal shunt regulator where the TOTAL current
(resistor dividers + active device) is 20uA.

stacks. And the 50 ns is either specified as t...
Just visited the Mouser website and found this
Looks like the world of free EDA tools is getting interesting. I
wonder when Newark will include simulation i...
