Development of a high-speed digital signal process system for bunch-by-bunch feedback systems

Physical Review Special Topics. Accelerators and Beams, 2000
High-speed digital filter systems for bunch-by-bunch feedback systems have been developed at KEK. A two-tap finite impulse response filter with simple hardware realizes the functions of a 90° phase shift, suppression of the static component and digital ...

Photonic analog-to-digital converters

Optics Express, 2007
This paper reviews over 30 years of work on photonic analog-to-digital converters. The review is limited to systems in which the input is a radio-frequency (RF) signal in the electronic domain and the output is a digital version of that signal also in the electronic domain, and thus the review excludes photonic systems directed towards digitizing ...

An Improved Linearization Circuit Used for Optical Rotary Encoders

Measurement Science Review, 2017
Optical rotary encoders generate nonlinear sine and cosine signals in response to a change of angular position that is being measured. Due to the nonlinear shape of encoder output signals, encoder sensitivity to very small changes of angular position is ...
