The precise clock source is crystal oscillator made of 74hc04 ; the mute circuit can conceal the error and solve the problem of noise ; the antenna switching circuit in the receiver is to select one antenna from two which receives signal better. it can improve the quality of the receiving audio signal, restrain the noise effectively and promote the system performance
高精度的時鐘源是由74hc04構成的晶體振蕩器;靜音電路將出錯的音頻信號進行差錯掩蓋，很好地解決了噪聲問題;接收機採用兩副天線切換工作，提高了音頻信號接收質量，有效地抑制干擾，提升了系統的性能。 -
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
首先介紹了中頻數字接收機採用的過采樣數字混頻數字接收方案，然後給出數學模型，從理論上論證了該方案的可行性;二、數控振蕩器設計與實現。
