An IIR system with system function H(z)=(B(z))/(A(z)) is called a minimum phase if:
A. All poles and zeros are inside the unit circle
B. All zeros are outside the unit circle
C. All poles are outside the unit circle
D. All poles and zeros are outside the unit circle
Answer:A
An IIR system with system function H(z)=(B(z))/(A(z)) is called a minimum phase if:
A. All poles and zeros are inside the unit circle B. All zeros are outside the unit circle C. All poles are outside the unit circle D. All poles and zeros are outside the unit circle
Explanation: For an IIR filter whose system function is defined as H(z)=(B(z))/(A(z)) to be said a minimum phase,
