WebMay 17, 2024 · Implement Symmetric FIR Filters Using the DSP Slices . A simplified block diagram for the DSP slice of Figure 5 is shown in Figure 6 below. Figure 6 . This simplified … In signal processing, linear phase is a property of a filter where the phase response of the filter is a linear function of frequency. The result is that all frequency components of the input signal are shifted in time (usually delayed) by the same constant amount (the slope of the linear function), which is referred to as the group delay. Consequently, there is no phase distortion due to the time delay of frequencies relative to one another.
WebSo to get the phase response, we find the z-transform, replace z with e j ω and solve for the angle. Consider then the z-transform for a simple symmetric odd length (Type 1) FIR Filter with coefficients as: [ c 1, c 2, c 3, c 2, c 1] The z-transform would be: H ( z) = c 1 + c 2 z − 1 + c 3 z − 2 + c 2 z − 3 + c 1 z − 4.
