Lattice Phase Equaliser
... A lattice phase equaliser or lattice filter is an example of an all-pass filter ... That is, the attenuation of the filter is constant at all frequencies but the relative phase between input and output varies with frequency ... The lattice filter topology has the particular property of being a constant-resistance network and for this reason is often used in combination with other constant ...
All-pass Filter - Passive Analog Implementation - Lattice Filter
... The lattice phase equaliser, or filter, is a filter composed of lattice, or X-sections ... The filter is an example of a constant-resistance network (i.e ...
Lattice Phase Equaliser - Design
... The essential requirement for a lattice filter is that for it to be constant resistance, the lattice element of the filter must be the dual of the series element with respect to the characteristic ... Z is purely reactive such that Z = iX then the phase shift, φ, inserted by the filter is given by, The prototype lattice filter shown here passes low frequencies without modification but phase shifts high ... At high frequency the lattice filter is a cross-over network and will produce 180° phase shift ...
