Description: 用LPC213X系列的PWM来产生语音。语音数据来源于PC机转换后得到的。最大可以是16位的。
由于是PWM所以输出端口需要低通滤波才能够得到比较干净的声音。
可以经过修改使用LPC2132以上的ARM的D/A来产生。
This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM. -LPC213X series used to generate the PWM voice. Voice data from the PC after the conversion. It is the largest of 16. Because there is PWM output ports need low-pass filter can be relatively clean voice. It has been modified over the use LPC2132 ARM D / A to produce. This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM.

Description: PWM原理
2、调制器设计思想
3、具体实现设计
一、 PWM（脉冲宽度调制Pulse Width Modulation）原理：
脉冲宽度调制波通常由一列占空比不同的矩形脉冲构成，其占空比与信号的瞬时采样值成比例。图1所示为脉冲宽度调制系统的原理框图和波形图。该系统有一个比较器和一个周期为Ts的锯齿波发生器组成。语音信号如果大于锯齿波信号，比较器输出正常数A，否则输出0。因此，从图1中可以看出，比较器输出一列下降沿调制的脉冲宽度调制波。
-PWM principle
2, modulator design ideas
3, concrete realization of the design
1, PWM (Pulse Width Modulation Pulse Width Modulation) principle:
Pulse-width modulation wave is usually a rectangular pulse duty cycle of different composition, its duty cycle and the signal is proportional to the instantaneous sampling value. Figure 1 shows the pulse-width modulation system block diagram and waveform diagram. The system has a comparator and a cycle composed of Ts of the sawtooth generator. If the voice signal is greater than sawtooth signal, the comparator output of the normal number of A, otherwise output 0. Thus, as can be seen from Figure 1, the comparator output a falling edge pulse width modulation wave modulation....
