Barcode Creation In .NET Framework Using Barcode generator for Visual Studio .NET Control to generate, create barcode image in .NET applications. A system is said to be memoryless if the output at any time depends on only the input at that same time. Otherwise, the system is said to have memory. An example of a memoryless system is a resistor R with the input x ( t ) taken as the current and the voltage taken as the output y ( t ) . The inputoutput relationship (Ohm's law) of a resistor is Reading Bar Code In .NET Framework Using Barcode recognizer for VS .NET Control to read, scan read, scan image in VS .NET applications.

A second example of a system with memory is a discretetime system whose input and output sequences are related by Draw Bar Code In VS .NET Using Barcode maker for .NET framework Control to generate, create barcode image in .NET framework applications. Create Code 128 Code Set B In VS .NET Using Barcode encoder for VS .NET Control to generate, create Code128 image in .NET framework applications. D. Causal and Noncausal Systems: A system is called causal if its output y ( t ) at an arbitrary time t = t,, depends on only t the input x ( t ) for t I o . That is, the output of a causal system at the present time depends on only the present and/or past values of the input, not on its future values. Thus, in a causal system, it is not possible to obtain an output before an input is applied to the system. A system is called noncausal if it is not causal. Examples of noncausal systems are Barcode Creation In .NET Framework Using Barcode generation for Visual Studio .NET Control to generate, create bar code image in VS .NET applications.

Note that all memoryless systems are causal, but not vice versa.

(1.60) satisfies the following two conditions, then T is called a linear operator and the system represented by a linear operator T is called a linear system: 1. Additivity: Given that Tx, = y , and Tx, for any signals x , and x2.
2. Homogeneity (or Scaling): = y,, then
T{x, +x2) = y , +Y, for any signals x and any scalar a. Any system that does not satisfy Eq. (1.66) and/or Eq. (1.67) is classified as a nonlinear system. Equations (1.66) and ( 1.67) can be combined into a single condition as (1.68) T { ~+ w 2 ) = ~ I Y + a 2 Y z I I where a , and a, are arbitrary scalars. Equation (1.68) is known as the superposition property. Examples of linear systems are the resistor [Eq. (1.6111 and the capacitor [Eq. ( 1.62)]. Examples of nonlinear systems are (1.69) y =x2 y = cos x
(1.70) Note that a consequence of the homogeneity (or scaling) property [Eq. (1.6711 of linear systems is that a zero input yields a zero output. This follows readily by setting a = 0 in Eq. (1.67). This is another important property of linear systems. TimeInvariant and TimeVarying Systems: A system is called rimeinuariant if a time shift (delay or advance) in the input signal causes the same time shift in the output signal. Thus, for a continuoustime system, the system is timeinvariant if for any real value of shiftincariant ) if For a discretetime system, the system is timeinvariant (or ~ { x [ n ] ) = y [ n  k ] k (1.72) for any integer k . A system which does not satisfy Eq. (1.71) (continuoustime system) or Eq. (1.72) (discretetime system) is called a timevarying system. To check a system for timeinvariance, we can compare the shifted output with the output produced by the shifted input (Probs. 1.33 to 1.39). Linear TimeInvariant Systems
If the system is linear and also timeinvariant, then it is called a linear rimeinvariant (LTI) system. CHAP. 1 1

H. Stable Systems: A system is boundedinput/boundedoutput (BIBO) stable if for any bounded input x defined by
the corresponding output y is also bounded defined by
where k , and k, are finite real constants. Note that there are many other definitions of stability. (See Chap. 7.) I. Feedback Systems: A special class of systems of great importance consists of systems having feedback. In a feedback system, the output signal is fed back and added to the input to the system as shown in Fig. 116.
