Signals in the frequency domain

Research output: Chapter in Book/Report/Conference proceedingChapter


Interpreting signals in the time domain is intuitively grasped by most people as time plots are commonly encountered in everyday life. Time domain plots represent the variable of interest in the y-axis and time in the x-axis. Stock charts show the up and down trends of your investment's value over time. Your electric company bill will show your power usage month-to-month over the course of the year. Signals in cardiology are also most commonly displayed in the time domain. ECG and blood pressure monitors, for example, continuously plot voltages or pressure vs. time.
