发帖数: 22800 | 1 short answer: integrated amplifier= power amp + pre-amp
long answer:
"A power amp usually just takes one signal input (or two for stereo) and
amplifies it so that it can drive a speaker.
An preamp takes several
inputs, provides a mechanism to switch between them, a volume control,
some sort of tone and balance control (usually but not always), and puts
out a single signal at line level. You plug your sources into the
preamp, plug the preamp into the power amp, and the power amp into the
speakers... 阅读全帖 |

发帖数: 2005 | 2 Functionality wise, receiver = pre-amp + power amp.
pre-amp's purpose is to process the signal, and power amp is to amplify the
signal and drive the speakers.
If receiver doesn't have enough power, then just replace it with another
more powerful receiver.
If you want to connect a receiver to another receiver, you should connect
the first receiver's pre-amp output to the secnond receiver's input. I don't
think you can connect the first receiver's powered output to the second
receiver's input. The... 阅读全帖 |

Power system can be divided into even more areas. In general, needs very

power clean还比较简单，先练了下硬拉耸肩两组，翻臂两组，front squat两组, 然后

然后，就开始玩power snatch, 发现这个不是一般的难掌握啊，先试了直接抓起，75磅
都觉得不稳，然后举着深蹲，平衡非常难掌握，浑身发抖。
问问，power snatch, 有什么更好的分组练习方法吗？另外，有什么诀窍，该特别注意

发帖数: 208 | 22 本人是学EE power方向的，现在是硕士第一年，预期明年八月份毕业。现在的方向是
power system， 非power electronics或者electric machine。由于一些原因，以后肯
定是要回国发展的，只是时间问题。
Power方向在美国的学校里很少，我所在的学校水平这方面还算不错。根据组里的情况
，今年即将毕业的硕士都拿到了几个大的电力企业的offer。
我自己对于现在的研究不能说是有多么的热爱或者痴迷，但至少并不讨厌，而且学了好
几年感情也很深厚了。
我自己的考虑综合别人的一些意见是：
读phd的原因：
1. 行业特殊性：国内的电力行业主要还是由国家垄断，美国的MS加上几年从业经验回
去之后也没什么优势。现在很多硕士的同学做实习的内容大多都是编程序写代码，离
Power的核心主业有点远。当然海龟博士和国内博士相比也没有明显的优势，但要比硕
士的情况好一些。
2. 个人倾向于在工业界发展，但并不排除将来在高校发展的可能。
3. 在经济方面暂时并没有特别多的要求，不是说我不缺钱，只是经济利益在我的考虑
中排得比较靠后。（可能有点太理想主义了）。
根据前辈的建议： |

你只有dsp方面的知识,可以考虑做power electronics和motor control方面的数字化控

FPGA等.
但是要涉及到power系统级的设计,你的背景就很有限,基本不太可能成为project

会参与到硬件或者功率部分的设计,并且自己很努力补充这些知识,那么还是很有机会很

power electronics的control目前还主要是模拟的，但是motor drive很多是用

这个不一定会成功了。所以你这个，对自身的发展应该主要是embedded。
