作为一名广播电台的技术人员,必须时刻监听广播音频信号,保证节目的安全优质播出。而在实际工作中,技术人员不能做到时时监听电台音频信号,从而给安全播出工作埋下了隐患。为此,本台技术人员设计制作了广播电台音频信号自动检测告警器,用电子手段检测音频信号,在音频信号中断时能发出告警信号,极大地提高了安全优质播出水平。 As a radio technical staff, we must always monitor radio and television signals to ensure the safety and quality broadcast programs. In actual work, technicians can not always listen to radio audio signals, thus laying a hidden danger for safe broadcasting. To this end, the technical staff of our station designed and manufactured automatic audible alarm signals for radio stations to detect audible signals by electronic means. When the audible signal is interrupted, they can send out an alarm signal, which greatly improves the safe and high quality broadcast.
