Timing Diagrams — A graph of voltage (or logic level) versus time for one or more signals is called a timing diagram. Evaluate the statement.

Difficulty: Easy

Correct Answer: Correct

Explanation:


Introduction:
Timing diagrams are the primary way to visualize relationships among digital signals—setup/hold windows, propagation delays, pulse widths, and inter-signal timing constraints. This statement asks you to recognize that a voltage- (or level-) vs time plot is precisely a timing diagram.

Given Data / Assumptions:

  • Axes: time on the horizontal; voltage/logic level on the vertical.
  • Signals may include clocks, data, enables, resets.
  • Idealized or simulated waveforms are acceptable.


Concept / Approach:
A timing diagram captures temporal behavior—edges, widths, skew, and causality between signals—making it distinct from frequency-domain plots (spectra) and static DC transfer curves. It is used for specification (datasheets) and verification (simulation outputs).

Step-by-Step Solution:

1) Identify the plotted quantity (voltage/level) and the time axis.2) Confirm event sequencing (rising/falling edges, pulse timing).3) Recognize cross-signal relationships (e.g., data valid relative to clock).


Verification / Alternative check:

Compare with an oscilloscope/simulator waveform window; both are timing diagrams when plotted vs time.


Why Other Options Are Wrong:

Incorrect: The definition matches standard usage.True only for analog waveforms: Digital levels vs time are also timing diagrams.Only when plotted in the frequency domain: Frequency-domain plots are not timing diagrams.


Common Pitfalls:

Confusing eye diagrams (statistical overlays) with general timing diagrams.Ignoring that multiple signals may be stacked in one diagram.


Final Answer:

Correct
