What is Linear Phase Characteristics of FIR Filters about?

1) FIR filters have a finite impulse response where the coefficients h(n) are non-zero for a finite number of samples. 2) For a linear phase response, the phase shift θ(ω) must be a linear function of frequency. This results in a time-shifted version of the input signal as the output. 3) For the impulse response h(n) to satisfy the linear phase condition, it must be symmetric or anti-symmetric.
