minimumphase transfer function

[devnarayan]

for a minimum phase transfer function:-
1)all the poles is in left side of plane
2)all the zeros in the left side of plane
3)all the poles and zeros in the same side of plane
4)all the poles or zeros in right side of plane
please select correct option from given choice

I am sure all the poles and zeros has to be on the same side of plane! Now if you want a stable system in addition to minimum phase, obviously the poles and zeros have to be on the Left side of the plane. Since the question only asked for minimum phase and mentioned nothing about stability, option 3 is the answer!

sir thanks please help me to understand this problem also
i have two confusion
1) is x(t).δ(1)=x(t).δ(3)? by using property δ(-t)=δ(t) =»δ(-t+to)=δ(t+to)
2).The expression δ(-t-t0)*x(t0-t), = ?(where * stands for convolution )
