Recently there have been a series of design ideas published based on the topic of “processors” of PWM signals. The purpose of these processors is to minimize both the settling time in response to a ...

Editor’s note: I came across this excellent tutorial article on Digital Filter Design and I thought it would be an excellent guide for novices as well as seasoned veterans. I want to thank William H.

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 ...

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.
