单位冲激信号(unit impulse signal)是最基本的信号,定义如下: {δ(t)=0,t≠0∫−∞∞δ(t)dt=1δ[k]={1,k=00,k≠0 代码: k=-10:10;yd=(k==0);stem(k,yd);xlabel('k');ylabel('f[k]');title('unit impulse signal'); 图形: stem()函数是用来画离散信号图的,第一个参数表示横轴刻度...
そのため、k番目の入力で挿入されたステップへの応答のパラメーターの発展は、配列pOut(:,:,k)で与えられます。行ベクトルpOut(i,:,k)には、i番目のタイム ステップのパラメーター値が含まれます。 ヒント 任意の入力信号へのシステム応答をシミュレーションするには、lsimを使用しま...

此外,zplane()函数属于Signal Processing Toolbox,提供的功能与pzmap()和pzplot()相似,但是使用语法不一样。而且zplane只能用于discrete系统传输函数的分析。后面离散系统的分析我们会用到zplane(). [1] https://www.mathworks.com/matlabcentral/answers/509011-pzmap-vs-pzplot-vs-zplane ...
which handles both finite impulse response (FIR) and infinite impulse response (IIR) filters[1]. Here,X(z) is the Z-transform of the input signalx,Y(z) is the Z-transform of the output signaly,nais the feedback filter order, andnbis the feedforward filter order. Due to normalization...
