Using linear phase reconstruction algorithms ensures that the edges of a tumor or a fracture line are depicted with maximum clarity and without geometric distortion. While the passband exhibits perfect linearity, sharp transitions to the stopband can sometimes result in ripples near the cutoff frequency if not designed carefully.

Another consideration involves the stopband behavior. If the filter introduces non-linear phase, the trailing edge of one symbol can smear into the leading edge of the next, causing inter-symbol interference and forcing the system to slow down to maintain accuracy.
This principle is mathematically expressed through a specific symmetry in the filter coefficients, which forces the phase response to be a perfectly linear function of frequency. This uniform delay, known as constant group delay, means that the shape of an input signal is maintained in the output, albeit shifted in time, which is critical for applications where waveform distortion is unacceptable.

Conclusion on Design Philosophy. Similarly, in radar, linear phase filter s help maintain the shape of the returned pulse, which allows for more accurate determination of an object's position and velocity.
