FREQUENCY-RESPONSE ANALYSIS
mocha-java.uccs.eduThe above plots are in a natural scale, but usually a log-log plot is made This is called a “Bode plot” or “Bode diagram.” Reason for using a logarithmic scale Simplest way to display the frequency response of a rational-polynomial transfer function is to use a Bode Plot .

www2.optics.rochester.eduThe intensity looks like the plot below versus position y, where y. z. are the minimums (or zeros): Intensity . y. 1. y. 2. y. 3. Minimums (zeros, y. z) y . Minimums are caused by the destructive interference of plane waves diffracting off the edges of the slit. Destructive interference happens when two plane waves are out of phase to one another.

Resolution is when the character solves the main problem/conflict or someone solves it for him or her. Denouement (French: the action of untying): is the series of events that follow the plot's climax.
