WebA system is referred to as generalized linear-phase system if its frequency response can be expressed in the form, H d(!) = jH d(!)je j +j where and are constants. The symmetric impulse response of a linear phase lter can have an odd or even number of points, and can have an odd or even symmetry about the midpoint, leading to four lter types: 1 ... WebA 2-D linear phase or zero phase filter implemented by direct convolution uses the filter’s impulse response as coefficients. If a 2-D linear phase filter has a region of support, RN, where. and N1, N2, n1 and n2 are members of the set of integers ( N1, N2, n1, n2 ∊ 1 ), then the filter’s impulse response has the form.
