已知LTI系统的输入f(t)和冲激响应h(t),则系统的零状态响应为()。 A: f(t)h(t) B: f(t)·h(t) C: f(t)&h(t) D: f(t)*h(t)

已知某LTI系统的冲激响应h(t),则零状态下激励为f(t)的响应为 A: f(t)+h(t) B: f(t)h(t) C: f(t)*h(t) D: f(t)&h(t)

要使自由基聚合反应进行，必须满足（ ） A: ΔH＜0；︱ΔH︱＞︱TΔS︱ B: ΔH＞0；︱ΔH︱＞︱TΔS︱ C: ΔH＞0；︱ΔH︱＜︱TΔS︱ D: ΔH＜0；︱ΔH︱＜︱TΔS︱

Morgan was so excited

若y(t)=f(t)*h(t)，则y(-t)=f(-t)*h(-t).

若x(t)*h(t)= y(t)，则x(-t)*h(-t)= y(-t)

若y(t)=f(t)*h(t)，则y(﹣t)=f(﹣t)*h(﹣t)。()
