[問題]步階函數利用 MATLAB問題?已回收
各位matlab版大您們好
小弟是第一次在本版發文
小弟有一題題目想問版大
題目是這樣子的:
Find the output of the system with input x[n] =2{u[n+2]-u[n-12]}and impulse
response h[n]=0.9^n{u[n-2]-u[n-13]}
想法:
>>h=(0.9)^n[0:49]*ones(2,13);
>>x=2*ones(-2,12);
>>n=0:12;
>>y=conv(x,h);
>>stem(n,y);xlabel('n');ylabel('y[n]')
要跑模擬時，
軟體說此句(第一句)n沒有定義?!
小弟跪求版大的幫助
感激不盡~~
m(_ _)m
