Abstract

The invention provides a level control system for digital modulation and demodulation in D-wave communication. The system comprises a processor, a data demodulator M and a level control module, whichare connected. The data demodulator M comprises a DAIN interface connected with the level control module and a DAOUT interface connected with the processor. The level control module comprises a buffercircuit, an automatic gain control circuit and an attenuation circuit, which are connected in sequence. The level control system is novel in circuit design and high in logicality, meets input of a wide-voltage and low-frequency small signal, has a good buffering function for the input signal, and can realize voltage following and small power adjustment to realize signal stabilization; besides, the system has an automatic gain adjusting function and is wide in gain width; the system also has an attenuation function after automatic gain to ensure that the voltage level is attenuated to the required level, so that a stable and reliable effect is achieved; and the system is higher in overall receiving sensitivity and faster in circuit response, and can better meet the requirements of digitalmodulation and demodulation.

Description

technical field [0001] The invention relates to the field of signal processing, more specifically, to a level control system for digital modulation and demodulation in D-wave communication. Background technique [0002] With the rapid development of science and technology and information technology, digital processing technology has made great progress. It is widely used in computer industry, communication industry, multimedia industry and other fields. However, most of the current signal processing technologies have a greater effect on signal interference and distortion, making the output signal quality poorer. The digital processing technology has the advantages of fast data processing speed and high calculation accuracy. Therefore, the development of digital signal processing system is of great significance to reduce signal interference, noise and distortion, and improve signal quality. [0003] In digital signal processing, a digital modem is usually used. The signal i...
