How to design linear phase FIR filter?

The most straightforward approach to the linear phase FIR filter design is the frequency sampling method. After a design is completed, the amplitude response A (co) is specified at N typically equidistant points or frequency samples.

Which of the following FIR system has linear phase response?

FIR I and FIR II Types

Again, this system has linear phase (the quantity inside the parenthesis is a real quantity) and the phase delay is M/2 samples.

What is linear phase FIR system?

Definition. A filter is called a linear phase filter if the phase component of the frequency response is a linear function of frequency.

What is linear phase response?

Linear-phase describes the response of a filter. When a signal goes through a filter, it experiences a time delay or phase shift. In a “perfect” filter, all frequencies should experience the same time delay (known as pure time delay), which preserves the wave shape as much as possible.
