[amp_mcq option1=”Continuous time” option2=”Discrete time” option3=”Sampled time” option4=”All of the above” correct=”option3″]
The correct answer is: C. Sampled time
A trellis diagram is a graphical representation of a finite-state machine (FSM). It is used to visualize the state transitions of an FSM and the corresponding output symbols. The horizontal axis of a trellis diagram represents the discrete time steps at which the FSM transitions between states. The vertical axis represents the possible states of the FSM. The branches of the trellis diagram represent the possible output symbols that can be generated by the FSM in each state.
The following is a brief explanation of each option:
- A. Continuous time is not correct because the horizontal axis of a trellis diagram represents discrete time steps.
- B. Discrete time is not correct because the horizontal axis of a trellis diagram represents sampled time.
- D. All of the above is not correct because the horizontal axis of a trellis diagram represents sampled time, not continuous time or discrete time.
