Optical frequency combs, generated by means of self-referenced and stabilized mode-locked lasers, have enabled revolutionary progress in precision optical frequency synthesis and metrology 1,2,3,4.

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 ...

Filters are used in many applications to remove unwanted frequency components from incoming signals, enhance incoming signals, or both. In portable and non-portable medical applications, for example, ...

To correct oscillations in a machine,mechanical design improvements and electronic filters are typically employed.However, these solutions often deliver limited success. Engineers should ...

Digital signal processors (DSPs) continue to receive a great deal of attention in new product design. For example, digital filter design reflects the importance of understanding and using this ...
