| 1. | Firstly , the theory basis of if digital receiver is introduced , which includes over - sampling digital mixing receiving scheme and mathematic model with which the scheme is proved correctly . secondly , the numerically controlled oscillator ( nco ) is designed and realized
首先介绍了中频数字接收机采用的过采样数字混频数字接收方案,然后给出数学模型,从理论上论证了该方案的可行性;二、数控振荡器设计与实现。 |
