ha, i forgot about them too. but i probably wouldn't have gone either way. i don't think it should be too bad. test 3 should be pretty straight-forward. there are only a few topics from which he can ask questions...and none of them are hard.

as for the final, i don't think i'll be taking that because i don't want to go back over test 1 and 2 material...but, i would guess it would be similar to previous test questions...not too difficult

How do you determine the symbol rate that uses the entire band knowing the channel bandwidth?

On HW#8, Problem 2:
The channel bandwidth is 100kHz, which gives an fs=66.6kbaud

On '04 Quiz 3, Problem 3:
The channel bandwidth is 6MHz -> fs=3Ms/s

No explanation as to where these numbers came from

It was really sad on Tuesday. I was the only person there and I didn't have any questions for him... so we both just left right after he got there.


Also, who noticed the sign in the lobby today? I made an addition below, "Break = "

r = 0.5

W = (1 + r) * WN

W = 1.5 * WN

W = 100 kHz

WN = 66.7 kHz

fs' = WN = 66.7 kbaud

quiz 3 problem 3....

W = (1 + r)WN = 2fs ... and r = 1

2150-2156 MHz so that means the W is 6 mhz...(channel bandwidth) and therefore, Wn=Fs(bandpass)
and so w=2fs so fs=3Ms/s and Wn = 3MHz

That went alright. The 'final' part seemed way too easy. I was worried with how easily I got the first and the last.

final part was easy.

for some reason, questions 3, 4 on white really got me. q3 i just couldn't get after an hour of trying everything i could think of. by the time i was on 4, i was pissed tired and not in the mood, so i didn't put too much thought into it. quiz3 will def be the one to be dropped for me.

75

But on Q3:

99

hah, i was backwards. i completely stalled on Q3 and got a 70. but on the final i got a 99...yay!

but i kinda figured i was going to do worse on that one about half way through, so i knew it was going to be dropped and i just let it slide.

my raw average is an A..i wonder if he'll curve. i mean, i know he will, i just want my official grade

crappy and crappy. 66 and 72. i was surprised i did better on the final since i didn't prepare for that one...and apparently i made some big mistakes on quiz 3. luckily i did better on my first 2 tests, but a crappy hw average hurt me. my final average was 75.1...a C+ will do i suppose. i should have done work in this class.
