Matlab中的离散函数
我有以下功能和值集：
z(t): {R → [-2,3] | z(t) = sin(0.5×π×t) + cos(2×π×t) + 1
t = [-1 : 0.001 : 1]
z(n×Ts) = z(n)
Ts=0.01
没有找到相关结果

Ts = 0.01; t = -1:0.001:1; n = t./Ts; nSampled = nan(size(t)); nSampled(1:10:end) = n(1:10:end); zCont = @(t)(sin(pi*t/2)+cos(2*pi*t)+1); zZOH = @(n,Ts)(zCont(floor(n).*Ts)); zDisc = @(n,Ts)(zCont(n.*Ts)); figure; plot(t,zCont(t),'b','DisplayName','Continuous'); hold on; plot(t,zZOH(n,Ts),'r','DisplayName','ZOH'); stem(t,zDisc(nSampled,Ts),'k','DisplayName','Discrete'); legend('show');
