Chinese Digital PWM modules have come down in cost over the past few months, but picking a PWM module that will help you to do what you need actually means you have to think about a host of things, ...

PWM的应用可以说非常广泛，控制电机速度、灯光亮度、通信调制等众多领域。 PWM的问题小伙伴问的比较多，最近也在用PWM，这里就分享一下关于PWM的一些内容。 什么是PWM？ PWM：Pulse Width Modulation，脉冲宽度调制。 网上的解释很多，通过下图，你就能直观的理解 ...

这是发布在网站www.controlpaths.com上的一篇技术文章，链接：https://www.controlpaths.com/2022/01/31/ripple-suppression-circuit-for-pwm-dac/ 转发这 ...

脉冲宽度调制(PWM)是数模转换的绝佳基础。它的优点包括简单以及(理论上)完美的差分和积分线性。不幸的是，PWM需要波纹滤波，这往往会使其速度变慢，尤其是在需要高分辨率(8位以上)的情况下··· 脉冲宽度调制(PWM)是数模转换的绝佳基础。它的优点包括 ...

Pulse width modulation (PWM) control, which uses variable-width digital pulses to represent the amplitude of an analog waveform, has been around for decades. The first specialized PWM IC dates back to ...

我曾经发布过一篇非常有用的设计实例，用于将PWM DAC输出纹波滤除和衰减。然而，我最近想到了一种更好的方法，可以从最初的实例中榨取更多的性能，同时又不失去最初的简单性。 曾几何时(2017年)，我发布了一个简单的设计实例“Cancel PWM DAC ripple with analog ...

Last time, I showed you a simple PWM block and an open source UART core. This time, I’ll put these parts together to create a PC PWM output peripheral. With working code (working, at least, in ...

Murata has got together with German chip firm ZMDI to produce the Power Block, a small (13x17x11mm) module that includes all the components necessary to make a non-isolated 25A step down dc-dc ...
