Adabot: Hello Minerva - do you read me? Over.
Minerva: Hello Ada [static] It’s difficult to hear [static]
Adabot: Hello Minerva [static] - your signal is unclear please re-[static] , over.
Minerva: I can’t quite hear you Adabot. There’s too much noise!
Minerva: Sorry Adabot - there’s too much noise in the signal. I couldn’t hear you :(
Adabot: I know - I couldn’t hear you either.
Adabot: Plus - I was going to watch a movie, but it won’t play. Any idea why?
Minerva: Something around here might be creating noise and interfering with the wifi signal.
Adabot: Noise? I don’t hear any noise.
Minerva: Well, Adabot - sometimes there’s noise that we can’t hear. It’s not audio noise, it’s electrical noise and it can cause problems for wireless circuits like your laptop’s wifi …
Minerva: … or even our walkie talkies.
Adabot: Noise you can’t hear? Interesting. Where could it be coming from?
Minerva: Lots of things can create electrical noise, but the most common are device with motors in them..
Minerva: like say … this fan!
Adabot: Hmm - but the video still isn’t loading.
Minerva: Or … devices that use a lot of power and send out radio waves … or microwaves, did I just hear the microwave oven?
Adabot: Oh good - my popcorn’s done!
Minerva: And look - now that the microwave stopped, the video is loading just fine :)
Adabot: Excellent - we are now noise free!
Adabot: But why does electrical noise cause problems like that?
Minerva: Too much electrical noise can confuse or overwhelm a circuit. Engineers often have to work on reducing electrical noise in their circuitry because less electrical noise makes a circuit work better.
Adabot: Oh - just like how it’s hard for someone to do work when there’s lots of regular noise around.
Minerva: Exactly! OK - now that the wifi is working, let’s try the Walkie Talkies again.
Adabot: Hello Minerva Can you read me? Over.
Minerva: Loud and clear! So what was it you wanted to ask me?
Adabot: Oh right! Would you like to come over here and watch a movie with me?
