Abstract

We propose a generic integrated filtering and digitizing approach that can complete signal filtering and digitizing simultaneously based on periodic signal multiplying. The filtering response can be reconfigured flexibly by adjusting the temporal shape of the local periodic signal and/or the impulse response of photodetection. The principle and features of proposed structure are analyzed and experimentally verified in the electrical domain and the photonic domain. The system responses in line with the theoretical and simulation results are experimentally measured.
