数字信号处理一点疑惑拿一道例题说事.X(z)=z^2/[(z-1/4)(4-z)]用留数法做RES(X(Z)Z^(N-1
1.已知x,y,z满足2│x-y│+(根号2y-z)+z平方-z+(1/4)=0,求x,y,z值.
已知复数Z满足|Z-4|=|Z-4i|.且Z+(14-z)/z-1为实数,求z.
一道数奥题,(x+y-z)²+(y+z-4)=-|z+x-5|
z
x^2+y^2+z^2+4x+4y+4z+1=0,求x+y+z
x^2+y^2+z^2+4x+4y+4z+1=0求x+y+z
x^2+y^2+z^2+4x+4y+4z+1=0 求x+y+z
x+y+z=2 4x+2y+z=4 2x+3y+z=1
{x+2y+z=4,x+y+2z=-1,2x+y+z=1
x-y-z=-1 3x+5y+7z=11 4x-y+2z=-1 分别求出x=?y=?z=?
(x-2y+z)/9=(2x+y+3z)/10=-(3x+2y-4z)/3=1 连等,求x,y,z,
