hello I need help on this hw. problem 2.4 edition 5

(a) express y(t) as a function of x(t)
(b) verify your result by checking at least three points in time.
(c) express x(t) as a function of y(t)
(d) verify the results of part (c) by checking at least three points in time

 

...you should probably upload the problem statement too...

 

Mind readers have left the building.

 

ok, sorry i dont know how to upload a pic, how do i do it ?

hello i just posted the picture

 

Write out x(t).

 

thats the problem i dont understand it ??? i dont know how to approach it...

 

thats the problem i dont understand it ??? i dont know how to approach it...

x(t) has 4 distinct intervals.

Interval 1.
-10 <= t < -3
What is x(t) in this interval?

Interval 2.
-3 <= t < 4
What is x(t) in this interval?

Interval 3.
4<= t < 8
What is x(t) in this interval?

Interval 4.
8 <= t < 15
What is x(t) in this interval?

 

i can see the intervals, do i suppose to solve for t ?

am i suppose to solve for t ? u(t+3) ???
for the first one ? i have no clue!

 

I have been looking at it. And maybe I am wrong. The length of t is different for the two functions. x(t) is from -10 to 15. y(t) is from -15 to 15, so if x(t) is input to find y(t), then how do you find y(t) when x(t) does not exist in the interval from -15 to -10.

 

You will probably have to ignore the time interval t < -10 and just give y(t) from t > -10 .
