Abstract

The invention discloses an automatic broadcast station lag phenomenon suppression device, which comprises a signal receiving module, a signal adjusting module, an interference suppression module and an isolation module, and is characterized in that the signal receiving module receives an audio signal converted by a broadcast program and transmits the audio signal to the signal adjusting module; the signal adjusting module sequentially uses an amplifier and a detector to respectively amplify an audio signal and detect and adjust the amplitude of the audio signal and then transmits the audio signal to the interference suppression module; the interference suppression module compensates for and filters the amplified audio signal and then transmits the amplified audio signal to the input end of the isolation module; and the output end of the isolation module is connected with the input end of an analog-to-digital converter. Interference and clutter signals in audio signals can be well suppressed and eliminated, and it is ensured that an output signal has high purity and stability.

Description

Technical field [0001] The present invention belongs to the technical field automatically broadcast station, and more particularly to an automatic broadcast station Caton phenomenon suppressing means. Background technique [0002] Audio workstation can achieve real-time processing of audio signals, produced by the broadcast program into an audio signal to achieve program signals broadcast via broadcast station automatic real-time online, so it is aired system has held enough important role in the television broadcast automation . Automatic audio broadcast system typically includes a server station, recording studio, broadcasting station, audio switch, like FM transmitter. The main station is complete broadcast live news, live variety show, audience participation, live interactive tasks, and automatically broadcast it in accordance with pre-choreographed program when Shun, broadcast stations generally use the dual-system backup, a main one. Recording the program is completed the m...
