4.1 LTI Discrete-Time Systems in the Transform Domain · Such transformdomain- representations provide additional insight into the behavior of such systems It is easier to design and implement these systems in the transform-domain for certain applications We consider now the use of the DtFt and the z-transform in developing the transform- domain representations of an LTI system

Second order systems systems described by a second order differential equation Second order systems contain two kinds of energy storage elements: Lump mass and spring

Module 3 First Order System (1 hours) First order systems .Time response of first order systems .Proportional feedback control of first order systems

Outline Launch systems characteristics Launch systems selection process Spacecraft design envelope environments

Question: Are there sets of basic\ signals so that a) We can represent rich classes of signals as linear combinations of these building block signals b) The response of ltI Systems to these basic signals are both simp and insightful Fact: For LtI Systems(CT or dt) there are two natural choices for these building blocks Focus for now:

RESERVATION SYSTEMS Single channel shared by multiple users Only one user can use the channel at a time Need to coordinate transmissions between users Polling systems Polling station polls the users in order Polling to see if they have something to send station A scheduler ca

Coordinate Systems Today we cover: Definition of coordinates - Conventionalrealization of coordinates Modern realizations using spaced based geodetic systems (such as GPS)
