Question

Which of the following is an method for implementing an FIR system?

(a) Direct form

(b) Cascade form

(c) Lattice structure

(d) All of the mentioned

The question was asked in my homework.

My question comes from Structures for FIR Systems topic in portion Discrete Time Systems Implementation of Digital Signal Processing

Answer 1

Right option is (d) All of the mentioned

For explanation I would say: There are several structures for implementing an FIR system, beginning with the simplest structure, called the direct form. There are several other methods like cascade form realization, frequency sampling realization and lattice realization which are used for implementing and FIR system.
