If you already have the frequency response of the impedance of a
circuit over a bandwidth, it should be possible to largely correct for
differences in the reactance of a similar but less-than-perfec...

I was looking for a 0.75 to 0.8A fuse for a PSU I've built and there's
a very wide price difference in what seems to me to be similar fuses.
I've been curious as to why this is the case for a whil...

To get to a higher frequency, is it possible to just use a smaller cap
and/or resistor on op amp derivative taking circuits?

In Wes Hayward's book "Introduction to Radio Frequency Design" on page
116, the voltage reflection coefficient is given as gamma = V-/V+ =
(z-1)/(z+1) where z is the normalized impedance, Zin/Z_o. ...

I understand that they are different domains (Hz - analog and bits/sec
- digital), how would one
convert e.g., 1Gbit/s to corresponding Hertz
frequency ?

I have a Radio Shack count-up/count-down timer, catalog #63-878. It's
about 2.5"x3.2"x0.70" thick.
It's around 10 years old and some of the input keys had become sticky.
I had to remove the ba...

Hello,
I have a question about where do frequencies end and pulses start?
I'm trying to make an impact detection circuit, I have some sensors on
a mat, and when something strikes the mat I get ...

Hi,
this has nothing to do with electronics but since this group is very
active and professional, I bet someone knows.
My need is to make backups of certain files on my local disk to net.
I do...
