- 1.(t)=(t)*h()=f(-)h(t- r)drf(t)*H(t)=f(3t)*h(3t)=
- 2.6.已知y(t)=(t)* h(t)f(r)h(t- r)则f(-1)h(-t)f(t)* h(t)=f(3t)*h(3t)=
- 3.8.已知y(t)=(t)* h(t)f(r)h(t- r)则f(-1)h(-t)f(t)* h(t)=f(3t)*h(3t)=
- 4.55.已知y(t)=(t)* h(t)f(r)h(t- r)则f(-1)h(-t)f(t)* h(t)=f(3t)*h(3t)=
- 5.(t)=f()* h()=f()h(t-t)drf(3t)“h(3t)=
- 6.y(t)=f(t)* h()= f(r)h(t- r)d则f(-t)xh(-t)=f(t)*h(t)=(3t)*h(3t)=果请用y(t)表示)
- 7.()=f()* h()=f(r)h(t-r)df(t)* h(t)=f(3t)*h(3t)=
- 8.()=f()* h()=f(r)h(t-r)df(t)* h(t)=f(3t)*h(3t)=
- 9.()=f()* h()=f(-)h (t- r)d则f(-1)米h(-t=f(t)* h'(t)=f(3t)*h(3t)=果请用y(t)表示
- 10.y(t)=f() w h(t)= f()h(t- r)d则f(-1)*h(-t)f(t)* h(t)=f(3t)* h(3t)果请用y(t)表示
