ABCD The state-space description of the loop filter.
nlev The number of levels in the quantizer.
xlim A vector or scalar specifying the limit for each state variable.
ymax The stability threshold. Inputs that yield quantizer inputs above ymax
are considered to be beyond the stable range of the modulator.
umax The maximum allowable input amplitude. umax is calculated if it
is not supplied.
按照这里写的:指定每个 state 变量的限制的向量或标量。感觉写的比较抽象,我在b站看视频,听up讲的积分器的输出摆幅,不知道理解的对吗
但是我我发现,不用这个函数限制xlim和ymax反而积分器输入输出都小了很多,好奇怪
