The term “time domain” is used while describing functions or physical signals with respect to time either continuous or discrete. The time‐domain signals are usually more comprehensible than the frequency‐domain signals since most of the real‐world signals are recorded and displayed versus time. Common equipment is to analyze time‐domain signals is the oscilloscope. In Figure 1.1, a time‐domain sound signal is shown. This signal is obtained by recording of an utterance of the word “prince” by a lady. By looking at the occurrence instants in the x‐axis and the signal magnitude in the y‐axis, one can analyze the stress of the letters inside the word “prince.”
