Waveform interpretation The combined view of related digital waveforms (for example, clock and data across time) is commonly referred to as a ________.

Introduction / Context:
Digital designers visualize multiple signals together to understand their relationships—setup/hold, enable windows, bus transitions, and protocol events. The standard name for such a coordinated, time-aligned set of signal plots is a timing diagram.

Given Data / Assumptions:

• Multiple signals shown against the same time axis.
• Interest lies in relative edges, durations, and overlaps.
• Typical sources: logic analyzer captures or hand-drawn specification charts.

Concept / Approach:
A timing diagram is a graphical representation of logical levels as functions of time, typically across several channels. It helps verify protocol sequencing, ensure that constraints (like setup and hold times) are satisfied, and communicate expected behavior between design and verification teams.

Step-by-Step Solution:

Verification / Alternative check:
Logic analyzers and EDA tools export “timing diagrams” for buses and protocols (SPI, I2C, memory buses), reinforcing the terminology in practice and documentation.

Why Other Options Are Wrong:

• Simultaneous waveforms: Descriptive, not the established term.
• Two-phase waveforms: Describes a specific clocking style, not a general multi-signal view.
• Pulse waveforms: Too generic; any digital signal is a series of pulses.
• Event raster: Not a common digital design term.

Common Pitfalls:
Assuming timing diagrams show analog amplitude; they typically emphasize logic states and transitions, not precise analog voltage levels.

Final Answer:
a timing diagram
