事实证明，称为脉冲振幅调制（PAM）的简单脉冲调制技术比PWM更有效，并且对于PPM等单个脉冲而言，恒定功率。在PAM中，根据调制信号的幅度，各个脉冲的振幅变化。PAM调制器和解调器电路简单相比…

你有没有想过可能是t的父亲谁he glorious machines that make most of the casino revenues these days? A casino owner, a researcher, a young lad interested in gambling? None of these. It was a car mechanic who changed the face of gambling entertainment. Charles Fey from San Francisco came up with the first ever slot machine in the year 1887. Until 20th century term ‘slot machines’ was used not just to address gambling devices but also the automatic vending machines. These machines were called by unusual named like one armed bandit and fruit machine. Before your imagination starts running wild with the names, let me tell you that it is because prior to Fey’s invention, there were some poker machines that allowed the users to win free drinks or cigars on hitting the winning combination. These were also known as trade simulators because they paid winners in merchandise.

曾经想知道电线如何连接到连接器。如何连接到连接器段的不同数量的电线？像其他任何小工具一样，又称耳机，耳机，麦克风的连接器插孔在工程书中也具有同样有趣的章节。它是最便宜的部分之一，但在技术上不是劣等的部分。它值得从工程师的设计和质量来看。该连接器在移动，笔记本电脑，音乐播放器等设备上的信号中发挥着重要的一部分，到耳机和麦克风，反之亦然。即使是一个小问题，也可能导致该设备的典范体验。连接器具有三个触点/段/零件，称为尖端，环和套筒。因此，它也称为TRS连接器。

以前，在脑波应用中，我们使用大脑的注意力水平来控制电动机的速度。现在，是时候检查我们的研究了一些更多的实时应用程序，以检测日常生活中是否可以实际使用脑波了。目前，我计划触发与任何类型的脑浪相关的东西。在现实生活中，我们经常可能想知道患者（可能是我们的亲密关系）是否在睡觉。因此，我试图使用脑电波制作设备，通过该设备可以通过消息/呼叫的帮助来确定该人是否在睡觉。

In the previous articles, we discussed passive electronic components like resistors, capacitors, inductors, and transformers. The passive components are particularly useful in designing various analog circuits. The real fun of modern electronics begins with semiconductors and digital electronics. Electronics is all about signals (in the form of voltage or current) and processing signals by components…

控制器区域网络或协议是卫理公会教徒d of communication between various electronic devices like engine management systems, active suspension, ABS, gear control, lighting control, air conditioning, airbags, central locking etc embedded in an automobile.CAN initially developed for in-vehicle networking of automobiles has expanded its applications in various other industries. The application started for luxurious cars is now being used in heavy duty vehicles like trucks, buses, trains and rail vehicles. The unique feature of CAN that allows various electronic units to communicate with each other made it important in healthcare domain. For example intensive care units and operating rooms where time and communication is of utmost importance. Entertainment industry also used CAN protocols to improve features in studios to control lights and door system and to control stage of theatres, event halls etc. Gambling machines and toys are other examples in entertainment field. In the field of science the high energy experiments and astronomical telescope use CAN in embedded network.
