electromagnetic interference or Emi for short is a term that describes any
external effects that disturb electrical circuits by way of induction or
radiation and while that definition may have been a bit boring for some rest
assured that the EMP blasts from action in sci-fi films are coming later so stay
tuned cuz Graphics of extreme Emi generators like nuclear explosions and
like maybe even some fighter jets are coming for now let's return to the
everyday world with examples you'll be much more likely to have encountered
when you and your buddy could accidentally control each other's RC
cars in a race uh that buzzing humming
sound that you can hear from a speaker if a nearby cell phone rings or that
bizarre thing where one radio station can bleed right into another so you're
essentially listening to a Mormon preacher and hardcore Punjabi rap at the
same time now these types of interferers
could generally be classified as narrow band since the trouble stems from two
intended broadcast Transmissions that have essentially become entangled with
each other and while they're certainly annoying the good news is that they are
easily dealt with by switching between alternate broadcast channels breaker
breaker one Niner this is lus coming in with a big 104 there sir this channel is
for Police use only uh uh anyway or by shielding
conductive wiring that might turn into an accidental antenna the second main
type type of interference would be broadband and these kind of suck things
like lightning strikes and high voltage power lines are a little tougher to deal
with since the Emi that they spew out is from copious amounts of energy and
covers many fre frequencies something that a controlled and intentional signal
shouldn't do thanks to the regulatory bodies more on that later the good news
here is that even broad interferes like lightning won't interfere with
everything and as long as your sensitive junk isn't too close to uh strike the
effects will only last as long as the storm so then what is it lonus that
we're all worried about exactly Emi doesn't sound too bad and yeah actually
naturally it's not but for every Humanity advancing invention from some
like way heavy dude there's a countermeasure from some butthole to
junk it up Jammers can block Communications or even radar by taking
is on again trying to make a video here
can block Communications or even radar
by talking over all of the intentional
signals and to deliver on the nuclear explosions I promised at the top I'll uh
pause here while they throw those in real quick
the electromagnetic pulse which accompanies one of these behemoths can
actually be as devastating as the blast itself instantly frying sensitive
Electronics crippling the communications and responsibilities of those affected
some have even theorized that it would only take a couple dozen or so of these
things detonated in the atmosphere to essentially wipe out all of the world's
power sources including batteries bummer
so that settles it then right lonus nothing is safe and we should go back to
living scantily clad in the forest right wrong well mostly wrong anyway you see
Michael Faraday certified heavy dude brought us Faraday cages or Shields
devices that protect their contents from electrical disturbances by channeling
them around the exterior or in other words they bounce electromagnetic wave
activity off them and while these devices sound kind of complex really
they're just a metal or mesh container you know like the ones on the door of
your microwave and the ones that we already ship batteries back and forth in
now so you see as long as we continue to make sure that we don't overload
Wireless channels bandwidth like we did during the release of the first iPhone
be sure to place power sources away from hight traffic areas and keep potential
super villains in check through the use of sexy British intelligence agents
everything will be just fine that is unless of course an unpredictable solar
flare strikes us without warning speaking of unpredictable solar
flares actually nothing to do with those at all but they may make you appear to
be brighter as well the service that I'm talking about is of course linda.com
with a linda.com membership you can watch and learn from Top experts who are
passionate about teaching whether it's like digital photography or video
editing two things that we're pretty passionate here at lus Media Group about
or whether it's business or even just learning basic Office programs like
Microsoft Word you can stream thousands of video courses on demand and learn at
your own pace on your own schedule whenever it is you have time whether
you're trying to you know improve your ability in some hobby that you do or
whether you're trying to look for a new job or get a promotion at your current
one you can take notes as you go and refer to them later you can download the
tutorials and watch them On The Go including access on your iOS or Android
device and the best thing of course about linda.com actually the two best
