If M and N are the orders of numerator and denominator of rational system function respectively, then how many memory locations are required in direct form-II realization of that IIR filter?
A. M+N+1
B. M+N
C. Min [M,N].
D. Max [M,N].
Answer:A
If M and N are the orders of numerator and denominator of rational system function respectively, then how many memory locations are required in direct form-II realization of that IIR filter?
A. M+N+1 B. M+N C. Min [M,N]. D. Max [M,N].
Explanation: From the direct form-II realization of the IIR filter, if M and N are the orders of numerator and denominator of rational system function respectively, then Max[M,N] memory locations are required.
