Minimized Group Delay FIR Low Pass Filter Design Using Modified Differential Search Algorithm
Journal of Telecommunications and Information Technology, 2023 Designing a finite impulse response (FIR) filter with minimal group delay has proven to be a difficult task. Many research studies have focused on reducing pass band and stop band ripples in FIR filter design, often overlooking the optimization of group
