chirplet_analasis
针对信号自适应chirplet分解未知参数多、实现起来比较困难的特点,文献[1]提出了一种新的chirplet分解快速算法。该算法利用计算信号的二次相位函数,得到其能量分布集中于信号的调频率曲线上的结论,此时通过谱峰检测可同时获得chirplet调频率、时间中心和幅度的估计;然后通过解线性调频技术获得其初始频率和宽度的估计,仿真结果验证了本文算法的有效性。(this code includs one method for chirplet analasis,that is used in voice and ultra-wave analasys,etc.)

脉冲宽度调制(PWM)是英文“Pulse Width Modulation”的缩写,简称脉宽调制。它是利用微处理器的数字输出来对模拟电路进行控制的一种非常有效的技术,广泛应用于测量,通信,功率控制与变换等许多领域。一种模拟控制方式,根据相应载荷的变化来调制晶体管栅极或基极的偏置,来实现开关稳压电源输出晶 体管或晶体管导通时间的改变,这种方式能使电源的输出电压在工作条件变化时保持恒定。 脉冲宽
-Pulse width modulation (PWM) is the English " Pulse Width Modulation" acronym, or pulse width modulation. It is the use of the microprocessor to the digital output of analog circuits for the control of a very effective technology, widely used in measurement, communications, power control and many other fields with the transformation. An analog control means, in accordance with the corresponding changes in load modulation transistor gate or base bias, switching power supply to achieve the output transistors or transistor on-time changes in power in this way can the output voltage in the workplace conditions of constant change.
