  1. 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。
  2. 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。
  3. It can interface with single chip computer expediently and transmit data by rule and line. oscillator in the infrared transmitting circuit that consisted of ne555, and can used to modulates the output from serial port of single chip computer. the integrated infrared receiver can demodulates, filter and transmit the signal to single chip computer

    紅外線西北口二j匕大學悶成d匕學位咭侖文發送電路的振蕩器由ne555構成，它可對串列口輸出信號進行調制，一體化的紅外接收頭對紅外信號進行解調、濾波和整形，再送單片機處理。
  4. This paper analyses crystal oscillator ’ s character and technique targets, and the changes of these technique targets effect the time of crystal oscillator gives the error mode of crystal oscillator time, by discussing gps system and time service theory, we analyze random character of gps second pulse error. we combine long - time stability of receiver ’ s output signal and short - term stability

    該系統成功地應用於寬頻帶地震記錄儀中，使地震數據記錄的時基精度達到微秒級，可以解決大范圍的地震儀布設應用時的授時和空間定位（經度、緯度、海拔）問題，為地震數據記錄、分析工作提供了與國際標準時間同步的時間基準。
  5. A full - digital demodulation technique is introduced in this paper, which can make it easy and quick to design and achieve binary phase shift keying ( bpsk ) demodulator, and also can reduce the requirement of the oscillator frequency precision and the degree of stability of the receiver
