Module B- Assignment 2

Topic #1

Part A:

Police Radio Jammer- Blocks signal from police radar guns and also, unintentionally blocks signal from wireless networks.

Signal Jammers- Used in hospitals to ensure that if a cell phone goes off it won't interfere with a procedure that is going on.

Concrete Blocks- Blocks signals because of its thickness, used for constructing concrete walls, such as walls of schools or in basements.

Microwaves- Particles that are emitted from the microwave can cause a computer's signal to be disconnected.

Part B:

Signal Jammers: To avoid a signal jammer's EMI you have to move away from it. Its not going to stop jamming signals just for you.

Police Radio Jammers: To avoid a police radio jammer's EMI you would have to turn it off. But doing so you risk getting caught for speeding by the police.

Concrete Blocks: To avoid a concrete block's EMI you would have to either re-build the wall with concrete blocks and use something that isn't going to emit EMI or by a signal booster.

Microwaves: To avoid a microwave's EMI you have to move the router that is connected between the computer and the microwave. So that the microwave's emmitted particles wouldn't interfere with the computer's wireless signal.

Hi Breeanne:

Here we go...

A. Research the types of devices that can cause electromagnetic interference (EMI)--must include a minimum of 4 devices

Offers minimum 4 devices -- 4/4 marks (1 mark each)

Presents a brief description of each (2-3 sentences) -- 3 x 4 = 12/12 marks

B. Research ways to reduce EMI from the devices you state.

Offers a brief and adequate solution for each -- 4 x 2 = 6/8 marks
-not sure what you mean by "mov[ing]" away from it...

TOTAL: 22/24 marks
