Design of High-speed Sampling System in Pulse Laser Application

4 HIGH SPEED SAMPLING AND HIGH SPEED ADCs , Walt Kester

High speed ADCs are used in a wide variety of real-time DSP signal-processing applications, replacing systems that used analog techniques alone. The major reason for using digital signal processing are (1) the cost of DSP processors has gone down, (2) their speed and computational power has increased, and (3) they are reprogrammable, thereby allowing for system performance upgrades without hard...

Performance Optimization Design for a High-Speed Weak FBG Interrogation System Based on DFB Laser

A performance optimization design for a high-speed fiber Bragg grating (FBG) interrogation system based on a high-speed distributed feedback (DFB) swept laser is proposed. A time-division-multiplexing sensor network with identical weak FBGs is constituted to realize high-capacity sensing. In order to further improve the multiplexing capacity, a waveform repairing algorithm is designed to extend...

Design of Parallel Crc Generation for High Speed Application

Error detection is important whenever there is a non-zero chance of data getting corrupted. A Cyclic Redundancy Check (CRC) is the remainder, or residue, of binary division of a potentially long message, by a CRC polynomial. This technique is ubiquitously employed in communication and storage applications due to its effectiveness at detecting errors and malicious tampering. The hardware impleme...
