Hey guys, could one of you please tell me HOW to do this question, i have absolutely no idea

thanks

Samples at t=2, 3 and 4
t=2, f(t)=2
t=3, f(t)=4
t=4, f(t)=1

2 in binary is 010
4 in binary is 100
1 in binary is 001

Thus the digital signal generated would be: 010 100 001
So answer is B

 

[jake2.0]

aahh crap! u have to know binary, i thought that finished in year 10!

 

[香港!]

hehehe, but Binary is also learnt in Year 11

 

[steelite]

Can someone list them all, l completely forgot about binaries as well

 

[brownsound]

we only need to now how binary to dec and dec to binary dont we?
we dont need to now addition and multiplication?

 

[karen88]

omg... never really learnt how to do binary!!!! could someone teach me!!!

 

[word.]

I'm pretty sure you don't need to know binary anymore at all...
but anyway I made this for my friend about a month ago so you guys can have it as well:

 

[karen88]

thnx for that... lets just hope theres no binary in it...

 

[香港!]

For Binary...
Basically just know it goes
..........2^6, 2^5, 2^4, 2^3, 2^2, 2^1, 2^0

so if u have like 001, that's (0 x 2^2)+(0x2^1)+(1x2^0)=1
1001 would be (1x2^3)+(0x2^2)+(0x2^1)+(1x2^0)=8+1=9
like that

 

[Famine]

Woot, thats a pretty good way of explaining it 香港!

I get it

 

[xand]

Help!!!!

Holy shit... I have no fucking clue what both that explanation means, or the other one with the ^ symbols... please help me? I dropped maths in yr 11 and genuinely do not have a single mathematical ability within me... please, by the end of the night, for the love of god someone help me...

Sincerely

2^0 means two the the power of 0
2^0=1
2^1 means to the the power of 1
2^1=2

it goes on like that..

 

[DoubleD]

^ means to the power of, so x squared is x^2
IF you dont know what that is.... then i'm glad you dropped maths.
