Another method for performing convolutions, which we call the slide rule method, is particularly convenient when both x ( n ) and h ( n ) are finite in length and short in duration. The steps involved in the slide rule method are as follows: Write the values of x ( k ) along the top of a piece of paper, and the values of h (  k ) along the top of another piece of paper as illustrated in Fig. 17. Line up the two sequence values x ( 0 ) and h(O), multiply each pair of numbers, and add the products to form the value of y(0). Slide the paper with the timereversed sequence h ( k ) to the right by one, multiply each pair of numbers, sum the products to find the value y ( l ) , and repeat for all shifts to the right by n > 0. Do the same, shifting the timereversed sequence to the left, to find the values of y ( n ) for n i0 .

The convolution sum expresses the output of a linear shiftinvariant system in terms of a linear combination of the input values x ( n ) . For example, a system that has a unit sample response h ( n ) = a n u ( n )is described by the equation Data Matrix Printer In Visual Basic .NET Using Barcode printer for Visual Studio .NET Control to generate, create Data Matrix 2d barcode image in .NET applications. USS Code 128 Recognizer In Visual Basic .NET Using Barcode reader for Visual Studio .NET Control to read, scan read, scan image in Visual Studio .NET applications. Although this equation allows one to compute the output y ( n ) for an arbitrary input x ( n ) , from a computational point of view this representation is not very efficient. In some cases it may be possible to more efficiently express the output in terms of past values of the output in addition to the current and past values of the input. The previous system, for example, may be described more concisely as follows: Create 1D In VB.NET Using Barcode generator for .NET framework Control to generate, create Linear 1D Barcode image in VS .NET applications.

Equation (I. l o ) is a special case of what is known as a linear constant coeficient difference equation, or LCCDE. The general form of a LCCDE is Generating UCC.EAN  128 In Visual Studio .NET Using Barcode generation for VS .NET Control to generate, create EAN / UCC  13 image in Visual Studio .NET applications.

If the difference equation has one or more terms a ( k ) that are nonzero, the difference equation is said to be recursive. On the other hand, if all of the coefficients a ( k ) are equal to zero, the difference equation is said to be nonrecursive. Thus, Eq. ( 1 . l o ) is an example of a firstorder recursive difference equation, whereas Eq. ( 1 . 9 ) is an infiniteorder nonrecursive difference equation. Difference equations provide a method for computing the response of a system, y ( n ) , to an arbitrary input x ( n ) . Before these equations may be solved, however, it is necessary to specify a set of initial conditions. For example, with an input x ( n ) that begins at time n = 0 , the solution to Eq. ( 1 . 1 1 )at time n = 0 depends on the SIGNALS AND SYSTEMS

values of y (  l ) , . . . , y (  p ) . Therefore, these initial conditions must be specified before the solution for n 2 0 may be found. When these initial conditions are zero, the system is said to be in initial rest. For an LSI system that is described by a difference equation, the unit sample response, h(n), is found by solving the difference equation for x ( n ) = 6(n) assuming initial rest. For a nonrecursive system, a ( k ) = 0, the difference equation becomes and the output is simply a weighted sum of the current and past input values. As a result, the unit sample response is simply Thus, h(n) is finite in length and the system is referred to as a fmitelength impulse response (FIR) system. However, if a ( k ) # 0, the unit sample response is, in general, infinite in length and the system is referred to as an infinitelength impulse response (IIR) system. For example, if the unit sample response is h(n) = anu(n). There are several different methods that one may use to solve LCCDEs for a general input x(n). The first is to simply set up a table of input and output values and evaluate the difference equation for each value of n. This approach would be appropriate if only a few output values needed to be determined. Another approach is to use ztransforms. This approach will be discussed in Chap. 4. The third is the classical approach of finding the homogeneous and particular solutions, which we now describe. Given an LCCDE, the general solution is a sum of two parts, where yh(n) is known as the homogeneous solution and y p ( n ) is the particular solution. The homogeneous solution is the response of the system to the initial conditions, assuming that the input x ( n ) = 0. The particular solution is the response of the system to the input x(n), assuming zero initial conditions. The homogeneous solution is found by solving the homogeneous difference equation
