Computationally efficient multirate passband equalization for bandpass digital/analog conversion
Dan P. Scholnik, J.O. Coleman · 2003
Many systems require a digital filter for decimation/interpolation and equalization of analog filtering. Under suitable conditions, iterative design of a low-rate, nonlinear-phase FIR filter and a cascaded high-rate, linear-phase FIR filter results in a computationally efficient filter structure.
