发射机电声指标主要指杂音电平、失真度和频率响应三大指标。这三大指标的好坏直接关系到播出质量,收听效果,同时也会影响到发射机运行的安全稳定。所以对可能发生的问题要防微杜渐,这也是保证安全播出的重要一环,高低周许多故障,往往首先表现为电声指标变坏,最后才酿成停播。因此,我们应把指标调整到最佳状态,以实 Transmitter electroacoustic index mainly refers to the noise level, distortion and frequency response of the three indicators. The quality of these three indicators is directly related to the broadcast quality, listen to the results, but also affect the safety and stability of the transmitter operation. Therefore, we should take precautionary measures against possible problems. This is also an important part of ensuring safe broadcasting. Many failures in the high and low weeks often show performance deterioration of the electroacoustic signals first and finally stop broadcasting. Therefore, we should adjust the indicator to the best condition to fulfill
