UNIT-I

Linear Time Invariant Systems A system satisfying both the linearity and the time-invariance property. LTI systems are mathematically easy to analyze and characterize, and consequently, easy to design. Highly useful signal processing algorithms have been developed utilizing this class of systems over the last several decades.

θ is the angle by which S 2 lands S 1.If β 1 = β 2 =90 o, the comparator is called cosine comparator and if β 1 =0 and β 2 =180 o, it is a sine comparator. In short, a phase comparator compares two input quantities in phase angle (vertically) irrespective of the magnitude and operates if the phase angle between them is < 90o. There are two types of phase comparators:

1.2 Second-order systems - MIT OpenCourseWare

Fluid systems store energy via pressure in fluid capacitances, and via flow rate in fluid inertia (inductance). In the following sections, we address models with two energy storage elements. The simple step of adding an additional energy storage element allows much greater variation in the types of responses we will encounter. The largest ...
