Correcting for Impedance Errors w/o Superposition & FFT [3 articles]
Bret Cahill - 2010-08-11 09:50:00
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...
Why such wide price difference in fuses? [5 articles]
Hammy - 2010-08-11 09:18:00
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...Linearily of Derivative Circuits At High Frequency [19 articles]
Bret Cahill - 2010-08-11 09:10:00
To get to a higher frequency, is it possible to just use a smaller cap
and/or resistor on op amp derivative taking circuits?

...Voltage Reflection Coefficient Question [3 articles]
Bitrex - 2010-08-09 04:12:00
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. ...Convert Bits/sec to Hz [19 articles]
Daku - 2010-08-09 02:51:00
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 ?

Joe - 2010-08-09 02:15:00
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.

panfilero - 2010-08-07 07:49:00
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 ...OT: File storing service (backup) in internet [2 articles]
Kari Laine - 2010-08-07 04:46:00
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...Linearily of Derivative Circuits At High Frequency
