【摘要】 介绍一种由多个音频编码的遥控系统，并按照该系统编码的指令格式，采用了四线一十六线译码器译码和大功率驱动开关集成电路进行指令输出的电路形式，成功地为机载遥控接收机设计了一种新的译码电路。该译码电路不仅具有元件少，功耗低；体积小，重量轻之特点，而且译码准确，抗单音频干扰性能优良，很适合于该设备的小型化。更多还原

【Abstract】 introduces a remote control system with a number of audio frequence coding,according to the order form of the system coding,using the decoder of having four lines-sixteen one todecode and the integrated circuit of driving switch of having large power,and carrying out the circuit form of order output,a new decoding circuit is designed successfully for the remote controlreceiver on the aircraft. The decoding circuit has not only characteristics of few components , lowconsumption of work, small volume and of light weight but also accurate decoding and good performance of resisting interference from single audio frequency. It fits to the small size of the equipment.更多还原
