सतत-समय स्थानांतरण फलन (continuous-time transfer function) Hc(s) = 1(s + 1)(s + 3) पर विचार कीजिए। विविक्त-समय स्थानांतरण फलन (discrete-time transfer function) Hd(z) प्राप्त करने के लिए 0.1 s के सैंपलिंग अंतराल के साथ एक द्विरैखिक रूपांतरण (bilinear transformation) का उपयोग किया जाता है। तो Hd(z) का मान है:
- 1(1 + z-1)2(21 - 19z-1)(17 - 23z-1)
- 2(1 + z-1)2(21 - 19z-1)(23 - 17z-1)✓
- 3(1 - z-1)2(21 - 19z-1)(17 - 23z-1)
- 4(1 + z-1)2(19 - 21z-1)(23 - 17z-1)
सही उत्तर देखें
(1 + z-1)2(21 - 19z-1)(23 - 17z-1)
