그림과 같은 이산치계의 z 변환 전달 함수 C(z)R(z)\dfrac{C(z)}{R(z)}를 구하면? 단, z[1s+a]=zz−e−az \left[ \dfrac{1}{s+a} \right]=\dfrac{z}{z-e^{-a}}이다.

1

2z2(z−e−T)(z−e−2T)\dfrac{2z^2}{(z-e^{-T})(z-e^{-2T})}

2

2z(z−e−T)(z−e−2T)\dfrac{2z}{(z-e^{-T})(z-e^{-2T})}

3

2zz−e−2T−2zz−eT\dfrac{2z}{z-e^{-2T}}-\dfrac{2z}{z-e^{T}}

4

2zz−e−T−2zz−e−2T\dfrac{2z}{z-e^{-T}}-\dfrac{2z}{z-e^{-2T}}
