The transfer function of the control system represented by the block diagram shown below is
On combining the blocks G_{2} and G_{3} which are in parallel, the given block diagram will be reduced as shown below.
Which one of the following block diagrams in options given is equivalent to the below shown block diagram?
The T.F. of the given block diagram can be reduced to:
Its block diagram is shown below, where a closed loop feedback system is transformed into an unity feedback system and viceversa,
Consider the following statements:
1. Transfer function is an expression which relates output to input in sdomain.
2. Transfer function gives information about the internal structure of the system.
3. A system can be represented by the block diagram if the transfer function of the system is known.
4. Block diagram is the flow of system variables from one block to another block represented by a single line.
Q. Which of the above statements is/are true?
Transfer function does not gives information about the internal structure of the system. Hence, staement2 is false.
The ratio C(s)/R(s) for the system shown in figure below is
On shifting the takeoff point beyond the block G_{3} and combining blocks G_{2} and G_{3}, the given block diagram is reduced as shown below.

Match ListI with ListII and select the correct answer using the codes given below the lists:
Consider the three block diagrams A, B and C shown below.
Q. Which one of the following statements is correct in respect of the above block diagrams?
Shifting the takeoff point after block G_{3} in block diagramA, the reduced block diagram will be as shown below.
Reducing further, the block diagram is reduced as shown below.
Thus, the block diagrams A and B are equivalent to each other.
