摘要
为了提高调幅广播监测仪的监测质量,针对原模拟接收监测仪温度漂移和非线性失真等不足,提出了一种基于DSP的调幅广播监测仪的数字化接收方法,克服了模拟前端超外差式接收监测仪的缺点,更适合未来的广播监测系统。
In order to improve the quality of AM monitor,a digital receiving method of AM monitor based on DSP without the defaults such as temperature excursion and nonlinear distortion is put forward, which will be suitable to the future AM monitor system.
