Statement-wise Verification

• Statement 1 - Correct.
  Transfer function is defined as ratio of Laplace transform of output to input under zero initial conditions.
  A transfer function is the Laplace-domain ratio of output to input for a linear time-invariant system under zero initial conditions.
• Statement 2 - Incorrect.
  It provides complete information about system internal states.
  A transfer function describes input-output behavior under zero initial conditions and does not uniquely reveal internal state realization
• Statement 3 - Correct.
  Poles of transfer function determine system stability.
  Its poles and zeros determine important input-output stability, transient and frequency-response features, but the transfer function does not uniquely reveal the internal state realization.
• Statement 4 - Correct.
  Zeros influence transient and frequency response characteristics.
  Its poles and zeros determine important input-output stability, transient and frequency-response features

Core Concept

A transfer function is the Laplace-domain ratio of output to input for a linear time-invariant system under zero initial conditions. Its poles and zeros determine important input-output stability, transient and frequency-response features, but the transfer function does not uniquely reveal the internal state realization.

Formula / Key Relationship

G(s)=Y(s)/U(s) with zero initial conditions.

Why the Other Options Are Wrong

Option A is incorrect because it includes incorrect statement(s) 2 and omits correct statement(s) 4. Option B is incorrect because it omits correct statement(s) 4. Option C is incorrect because it includes incorrect statement(s) 2 and omits correct statement(s) 1, 4.

Exam Shortcut / Approach

Poles are denominator roots; zeros are numerator roots.

Common Mistake

Transfer functions do not contain complete unique internal-state information.

Quick Revision

Poles Zeros and Zero Initial Conditions is linked with Transfer Function, System Modeling and Control Systems. Poles are denominator roots; zeros are numerator roots.
