## nijhu 3 years ago how will i convert a discrete signal from functional representation to a tabular form?

1. phi

do you have a specific function?

2. nijhu

yes

3. nijhu

lemme draw it

5. phi

That is just a description on how to come up with pairs of numbers n and x(n) The table would list all possible n's and the corresponding x value for that n

6. nijhu

ok

7. phi

what did you get?

8. nijhu

i have another question a finite duration sequence can be represented as x(n)={3,-1,-2,5,0,4,-1}

9. nijhu

there is an arrow below 2

10. nijhu

what is the meanining of it

11. nijhu

*meaning

12. phi

there is no 2

13. nijhu

sorry didnt get it

14. phi

15. nijhu

the topic is from a book called digital signal processing

16. phi

i have another question a finite duration sequence can be represented as x(n)={3,-1,-2,5,0,4,-1} there is an arrow below 2 there is no 2. Do you mean the -2? I would need more context, because that is not standard notation. It sounds like they are identifying the position of -2 for some purpose ?

sry my mistake it's -2
