Signal sampled at 5000 samples/s

[qwerty321]

ok i will post in here
I have a signal sampled at 5000 samples/s and I need to find the real values of the first 4 samples starting at t=0..
the signal is:

V=10 sin(8500t)
i do not understand the question..what shall i do?

If there are 5000 samples in 1 second, how much time elapses in between samples?

 

[qwerty321]

1/5000

 

[Redbelly98]

Okay, yes.

The first sample is at t=0.
Based on your answer of 1/5000, what is t for the next sample after that?

What is the signal at those values of t?

 

[qwerty321]

t is 2(1/5000) at t=1?

 

[Redbelly98]

No.

You get the first sample at t=0.
Then 1/5000 of time goes by, and it's time to get sample #2. What time is it? I.e., t=_____?

 

[qwerty321]

t=1?

 

[Redbelly98]

No, t=1 when 1 second has gone by.

Oh, I'm going to go offline soon, so you'll be on your own for a while.

i am lost..could you please resume..at t=0 we have 1/5000?

If you split 10 seconds into 10 different equal time slices, what is "t" at the beginning of each time slice, if "t" is in seconds?

Hint: t=0 is the start of the first time slice...what would t be for the start of the 2nd, 3rd, etc...
