[#96] The transfer function of a tachometer is of the form
Correct Answer
(A) $$Ks$$
[#97] A unity feedback system has $$Gleft( s
ight) = frac{{Kleft( {2s + 1}
ight)}}{{sleft( {4s + 1}
ight){{left( {s + 1}
ight)}^2}}}$$ What is the value of K if the steady-state value of error is to be less than 0.1 when an input r(t) = 1 + 5t is applied?
Correct Answer
(D) K > 50
[#98] If the output of the system at steady state doesn't agree with the input, then the system is said to have . . . . . . . . which determines the . . . . . . . . of the system.
Correct Answer
