Question

What is the overall transfer function for a closed-loop system having a forward-path transfer function of 5/(s + 3) and a negative feedback-path transfer function of 10?

Answer 1

• transfer function T(S)=
  `(5)/(S+53)`

Step-by-step explanation:

NEGATIVE FEEDBACK TRANSFER FUNCTION

negative feedback control of the amplifier is achieved by applying output voltage signal back to inverting input terminal by feedback

transfer function is T=
`(g)/(1+Gh)`

where G=forward Path gain

H=negative feedback gain

here G=
`(5)/(S+3)`

H=10

T(S)=
`(G)/(1+GH)`

=
`(5)/(S+53)`
