WebOct 30, 2024 · 卷积：f*g ( τ )=f (t)*g (t)= ∫ f (t)g(τ − t)dt =g (t)*f (t)=g*f ( τ) 卷积满足互换性，这是因为卷积在进行相关的点积计算前，固定f (t),将g (t)反向然后右移动 τ ，这时， g (t)与f (t)对向而行， τ 为正的方向 ;如果固定g (t),f (t)掉头与它对向而行进行点积计算， τ 为正的方向，计算结果没有不同。 互相关：R fg ( τ )= ∫ f (t)g(t + τ)dt = ∫ f (t − τ)g(t)dt =R gf (- τ) WebMay 30, 2024 · ∫f (t)δ' (t)dt ＝ ∫f (t)dδ (t) ＝ f (t)δ (t)-∫δ (t)df (t) 这步分部积分（见《微积分》或《高等数学》上册积分部分）完之后前面一项有取值为无穷的δ作差直接等于零，所以剩下后面一项 ＝-∫δ (t)df (t) ＝ -∫δ (t)f' (t) dt 根据δ函数性质（翻书吧，我也忘了） ＝ -f' (0) 上课少看手机，多少听点吧。 以上是丢人部分，我以为是乘号没想到是卷积。 卷积那就没问题 … WebSet up an integral for finding the Laplace transform of the following function: St. 8 f (t) t 3, 8 t help (formulas (eA (-st)) (t+3)dt where A 8 and B inf b.
