Design of digital filters by optimization techniques

Finite impulse response (FIR) and infinite impulse response (IIR) digital filter designs with optimization techniques are discussed in the report. An eigenvalue problem of trigonometric matrix is discussed in order to facility design of a new FIR filter with significantly reduced group delay. To des...
