A graph showing values at discrete time intervals is known as what type of representation?

The correct answer, which pertains to a graph that displays values at discrete time intervals, is "Digital." In digital representation, information is encoded in discrete (non-continuous) values. This means that rather than showing smooth changes as seen in analog signals, which can vary continuously and represent real-world phenomena, digital graphs show distinct steps or points.

Digital representation is fundamental in digital electronics as it enables the precise and reliable processing of data through binary values (0s and 1s). Each point on the graph corresponds to a specific time interval, showcasing changes in value only at those discrete moments, thus allowing for clear visualization of the data being represented.

Contrastingly, analog representation would depict values in a continuous manner, without any defined intervals, while continuous and static do not specifically define the concept of displaying values at discrete intervals. Continuous typically refers to signals that change fluidly over time, and static would imply a lack of change or movement altogether, neither of which captures the essence of a graph with values at specific, discrete time points.
