We analyse the output characteristic of a quantum high-pass/low-pass filter, which was introduced recently (Wang et al 2005 Phys. Rev. A 72 013822). Various responses of quantum filters with different parameters have been calculated. It is possible to apply these quantum circuits in quantum state preparation.
