訊號與系統單位步階函數題目
Oct 23rd 2013, 03:01

版主，這是 "訊號與系統單位步階函數題目"，所以應該跟方波有關。
但我兜不出一個方波滿足 u(-t) = 1-u(t)

不過，如果那個不知道什麼波的 u(t) 滿足 u(-t) = 1-u(t)
其他的都很好證明

(b)
u(3-t)
= u(-(t-3)) ... let s = (t-3)
= u(-s)
= 1-u(s)
= 1-u(t-3)

(c)
t u(-t) ... 代入 (a)，u(-t) = 1-u(t)
= t (1- u(t))

(d)
(t-3)u(3-t) ... 代入 (b)
=(t-3) (1 - u(t-3))
