Adjacent channel rejection is a key for comparing transient responses of filter Banks

This brief paper examines the most important differences between the responses of the Fast Fourier Transform (FFT) and Polyphase Discrete Fourier Transform (DFT) filter banks. In general, while the ...

On the application of spectral filters in a Fourier option pricing technique

When Fourier techniques are applied to specific problems from computational finance with nonsmooth functions, the so-called Gibbs phenomenon may become apparent. This seriously affects the efficiency ...

Building Soft Radio Channelizers Using Top-Down Design

Software-defined radios (SDRs) are adaptable transceiver systems that learn and adapt to transmission and channel environments with software. A key element of an SDR architecture is the channelizer, ...
