PURPOSE: To provide a delta-sigma modulator for digital/analog converter. CONSTITUTION: A digital signal having a plural bits is received by a converter 20. Two bits of these bits, i.e., the most significant bit and a 2nd bit which is neither the most significant bit nor the 2nd upper ...
Yes, in Simulink, you can use the Digital-to-Analog Converter (DAC) block to convert a digital signal (consisting of '0' and '1') into an analog signal. The DAC block is available in the Simulink library under the "Simulink > Ports & Subsystems" category. 댓글 수: 0 댓글...
在输出分辨率(PWM波的周期)一定的情况下,阶跃响应时间与输出稳定性呈现反比关系,当输出稳定性越高,即低通滤波器对PWM波一次谐波有越强的衰减特性,采用RC滤波器,此时,RC值越大。而RC值越大,系统的阶跃响应时间越长,动态输出效果越差。 一般策略: 一般实在保证阶跃响应时间的同时,使得电压输出的分辨率尽可能高。确定...

使用？你的意思是数字信号处理吗？因为自然模拟信号是连续的，所以如果需要控制、检测、滤波、调制等工作，则需要用将之转化成电子元件可识别的0，1模式数字信号，这样处理器或者电脑才能对之进行各种处理。当然不变成数字信号也是可以进行信号处理的 比如收音机，电视等就是直接对模拟信号进行解调放大。
Most electronic devices now include digital control circuitry (as illustrated by the recent Y2K problem), but analog values are still needed to control valves, loudspeakers, and other actuators. The conversion from digital to analog is usually accomplished within a dedicated D/A converter. This DAC...
