LINEAR SEQUENTIAL MACHINE AND REDUCTION OF LINEAR SEQUENTIAL MACHINE Linear Sequential Machines
(I) Time Domain (2) Frequency Domain Linear Sequential Machines
Module 2 Operation (0 and 1) and so on….. Linear Sequential Machines
Note: • A is always square matrix and gives number • of delays • Number of columns in B gives number • of inputs • Number of rows in C gives number of • output • Order of A and C should be compatible • with present state and order of B and D • should be compatible with input Linear Sequential Machines
Example 1: Linear Sequential Machines
State Space Representation: Linear Sequential Machines
Note: Y’s represent Next State y’s represent Present State z’s represent Output State Here, we have 3 delays, one input and two outputs Linear Sequential Machines
Representation: Linear Sequential Machines
Example 2: Determine Characterizing matrices A,B,C and D from the given linear circuit diagram Hint: From fig.,A=2 X 2,B=2 X 1,C=1 X 2 Linear Sequential Machines
From the figure, Y1 = y2 + x Y2 = y1 + x z = y1 + x Linear Sequential Machines

Reduction of Linear Sequential Machines Reduction of linear sequential machines means reducing or minimizing the number of delays Linear Sequential Machines
Example 3: Minimize (reduce) the linear machine given by following characterizing matrices A,B,C,D (Example Kohavi Page-580) Linear Sequential Machines
Reduction: The rank of the diagnostic matrix is 3, and hence the dimenstion of given linear machine CANNOT be reduced Linear Sequential Machines
