A Digital Receiver for Nuclear Magnetic Resonance Spectrometer
一体化核磁共振数字接收机的设计

A digital receiver for uses in nuclear magnetic resonance spectrometers was developed. Compared with the traditional ones, the digital receiver described in this study is capable of eliminating completely image peaks resulting from phase errors in the reference signals and unbalance in the gains between the two receiver channels. In addition, the digital receiver has features such as low cost, high flexibility, easy to use and small size. Detailed design strategy and experimental demonstration are given in the paper.
