Automatic Control Systems - Engineering

Q1:

Consider the following systems
System I,
System II,
where C(s) is the output and R(s) is the input of these systems

A System I has larger bandwidth and faster speed of response than System II

B System II has larger bandwidth and faster speed of response than System I

C System I has larger bandwidth but System II has faster speed of response

D System II has larger bandwidth but System I has faster speed of response

ANS:A - System I has larger bandwidth and faster speed of response than System II

Here time constant of both functions t is 1 for 1st and 3 for 2nd.

So t2>t1 and bandwidth are inversely proportional to time So b.w1 >b.w2, Therefore, option A is the answer.
