标题Re: [问题] 讯号与系统的小问题

The impulse response of the system is h(t)=2exp(-2t)u(t).
The output y(t) for input x(t)=tu(t) is tu(t)*h(t), where * stands for
convolution operation.
Can you make it?
※ 引述《miomio0322 (冒烟的LEO)》之铭言：
: 不好意思～因为初学 有个小地方看不太懂
: 所以想请大家帮个忙
: 有一题作业是
: A linear time-invariant system responds to the
: following inputs with the corresponding outputs
: IF x(t)=u(t),then y(t)=(1-exp(-2t))u(t)
: FIND y(t) for the following inputs
: 这小题是 x(t)=tu(t) 求y(t)
: 谢谢了～～～

1F：推 pjrz:也可以直接将 h(t)积分二次就是所求了 10/20 18:45
