Abstract

A new digital receiver is realized to elaborate signals from nuclear magnetic resonance (NMR). The proposed system replaces as much analog electronics as possible with digital electronics. The receiver can detect NMR signals in a frequency range of 0.5-90 MHz with direct detection and higher frequency with undersampling. The user can set parameters as bandwidth to be observed, gain of receiver and accumulation of results. Signal-to-Noise Ratio of the receiver chain is 60 dB. The system is realized on Field Programmable Gate Array (FPGA) on a Peripheral Component Interconnect (PCI) board. Experimental results obtained are presented.
