چکیده

he wide-spread and growing use of portable, battery-powered devices like cellular telephones, audio-capable personal digital assistants (PDAs), MP3 players and similar applications has resulted in an increasing demand for miniature, ultra low-power digital signal processing (DSP) technology. Many of these devices make heavy use of digital signal processing techniques like modulation, demodulation, filtering, automatic gain control, equalization and subband coding and decoding. In these devices, users expect a range of DSP-based features to be delivered with little impact on battery life and in miniature, portable packages.

Unified Pulsed Laser Range Finder and Velocimeter using Ultra-Fast Time-To-Digital Converter

In this paper, we present a high accuracy laser range finder and velocimeter using ultra-fast time-to-digital converter (TDC). The system operation is based on the measuring the round-trip time of a narrow laser pulse. A low-dark current high-speed PIN photodiode is used to detect the triggered laser beam and to produce start signal. The pulsed laser diode generates 45W optical power at 30ns du...
