单片机有着体积小、功耗低、功能强、性能价格比高、易于推广应用等显著优点，在自动化装置、智能仪器仪表、过程控制、通信、家用电器等许多领域得到日益广泛的应用。在许多基于单片机的应用系统中，系统需要实现遥控功能，而红外遥控则是被采用较多的一种方法。红外遥控是通过红外管发送红外遥控编码对其设备进行控制的,不同设备的遥控发送的红外遥控编码都是不同的。由于红外无线解决了有线连接的许多不便，因而受到了家电设备厂商、电脑外围设备商、以及通信设备厂商的高度重视。 如果将遥控技术、单片机与D类音频功率放大器结合起来，那么得到的产品将是非常前沿的。本次设计就是全遥控数字音量控制的D 类功率放大器。 -Single chip has a small size, low power consumption, functionality, and high cost performance, easy to promote the use of such significant advantages, in the automation device, smart instrumentation, process control, communications, household appliances and many other fields have been increasingly widely used. In many applications based on single-chip system, the system needs to achieve the remote control function, and infrared remote control is being used more methods. Infrared remote control by infrared remote control code to send IR control of their equipment, different equipment, remote control infrared remote control code sent is different. Infrared wireless solutions because of the cable
