Linear phase

Linear phase refers to a specific characteristic of filters, particularly digital filters, used in signal processing. In a linear phase filter, the phase response of the filter is a linear function of frequency. This means that all frequency components of the input signal are delayed by the same constant amount of time, leading to no phase distortion. ### Key Characteristics of Linear Phase Filters: 1. **Constant Group Delay**: Linear phase filters maintain a constant group delay across all frequencies.
