在实现微计算机广播与电视发射机等设备的自动控制中,计算机接口的采样电路的设计好坏,直接关系到微计算机能否正确地反映被控设备的工作状态及系统能否可靠地运行。采样电路设计应考虑到:信号取出部位最能反映被控设备该部分的性能;对采样信号进行处理的电路要尽可能的简单和可靠;
In the realization of micro-computer broadcasting and television transmitters and other equipment in the automatic control of the computer interface sampling circuit design is directly related to the micro-computer can correctly reflect the work of controlled equipment and the system can run reliably. Sampling circuit design should take into account: the signal extraction site can best reflect the performance of the controlled equipment part; the sampling signal processing circuit to be as simple and reliable as possible;
