应用背景 所有红外遥控器的输出都是用编码后串行数据对38～40kHz的方波进行脉冲幅度调制而产生的。如果直接对已调波进行测量，由于单片机的指令周期是微秒（μs）级，而已调波的脉宽只有20多μs，会产生很大的误差。因此先要对已调波进行解调，对解调后的波形进行测量。红外遥控接收芯片CX20106可以完成对遥控信号的前置放大、限幅放大、带通滤波、峰值检波和波形整形，只需加上简单的外围电路即可完成对已调波的解调 关键技术 用红外转发器控制电器，首先要进行对码，把要控制的家电遥控器对准红外转发器，把遥控器的功能键学习到红外转发器中，学习成功后，就可以控制了，例如，学习了空调遥控器的开、关，用POLYHOME智能主机操作空调开，主机发出射频信号到红外转发器，红外转发器把射频信号转成红外信号的“开”发射出去，就能把空调打开了，射频可以穿墙，红外信号是不能穿墙的，这就能实现远距离控制电器。
