Q.13) Transfer function of a continuous time causal LTI system is given by 1-e-se H(S)= Impulse response of this system is uniformly sampled by an impulse train of frequency 4 Hz to obtain impulse response of corresponding digital filter with transfer function Hz) Consider following statements H(s) is Re(s) > 0 JO 1. Continuous time system is unstable as ROC of which does not include axis H() is :| >1 II. Discrete time system is unstable as ROC of which does not include unit circle III. Area under impulse response of digital filter is 5 times in magnitude of the area under impulse response of continuous time system IV. Digital system works as a high pass filter Correct statement (S) is are Q.14) Unit step response of a unity feedback second order system is given (t)=1-3Be- sin ot-4Be- COS OL The value of damped frequency of oscillation (in rad/sec) is Q.13) Transfer function of a continuous time causal LTI system is given by 1-e-se H(S)= Impulse response of this system is uniformly sampled by an impulse train of frequency 4 Hz to obtain impulse response of corresponding digital filter with transfer function Hz) Consider following statements H(s) is Re(s) > 0 JO 1.
