Hence, notaPRF.
has a zero (s = 1) in RH s-plane.
Hence, not a PRF.
has a pole and a zero in RH s-piane.
Hence, not a PRF.
Option (b) is a PRF as all poles and zeros lie in LH s-plane.
Which of the following property does not relates to LC impedance or admittance functions?
If the impulse response is realisable by delaying it appropriately and is bounded for bounded excitation, then the system is said to be
Since system is bounded for bounded excitation therefore, it will be stable.
Since the system is delayed therefore, output may exist before the input is applied.
Hence, the system will be non-causal.
A network-A has zeros only in the left-half of the s-plane while the network-B has zeros only in the right-half of the s-plane. The network-A and Network-B will be respectively called
If F1(s) and F2(s) are positive real functions, then which of the following are positive real function?
For the pole-zero plot shown below, the network function is
Here, zeros are at: s = 0, 0,-3
Poles are at s = - 1,
or, poles are at (s + 2)2 + 1 - 0 and at s = -1 or, s2 + 4s + 5 = 0 and at s = -1
Which of the following is not a positive real function?
Here, a = 1 , b = 0, c = 2
Thus, a, b, c ≥ 0 but b < a
For PRF, b ≥ a therefore, option (d) is not a PRF.
