发帖数: 75 | 4 You may try to send a signal which is supposed to be in the image band.
Let's say the signal is at 1G+100MHz while the image should be in 1G-100MHz.
a CW tone with IQ phase will give you a output signal at 1.1GHz with a
power level 0dBm.
Now you shift the switch I Q input, such that I->Q, Q->I. The output signal
will appear at 900MHz, say, -30dBm power.
The modulator has an image rejection 30dB in this case.
Hope this is the answer you want.

发帖数: 52 | 5 学艺不精, 请高人指点.
需要设计12位input, 4位output的二阶SD modulator, output后面会连一个4位的DAC
和1.5KHz 的一阶LPF.
1. 4位输出, 取反, 反馈到输入, 扩展成12位的时候, 只要后面加零就可以了, 还是需
要更精确的按百分比去找对应? 代码用的是简单的2's complement.
2. 如果DAC是理想的, 给一个DC输入, full range -1V-1V, DAC VDD=1V, 最后输出波
的波动(noise)能控制在1mV以内吗?
3. noise都是高频的吗? 有否可能出现 <1.5KHz 的成分? 输出呈现某种pattern?
4. 二阶比一阶好在哪? 我觉得二阶的波形跳动幅度会更大?
多谢. |

这里我用deadband这个词可能并不恰当，其实我是在担心通过low pass
滤波器之后的信号上的ripple会不会使得modulator无法识别等效的DC信号？
对这个不知道你有什么看法？请赐教。
信号传输函数？这个可以解释详细一些吗？3x |

发帖数: 7639 | 7 哪位能指点一下怎么设计8PSK modulator最有效？
我现在的思路是
用serial/parallel电路把连续3个bit分开, b1 to Inphase,
b2 to Q-phase, b3 用来控制both Inphase/Qphase的pi/4延迟。
这样我的8PSK表达就是：
s_8psk(t) = b1 * cos(2*pi*fc*t + b3*(pi/4))
+ b2 * sin(2*pi*fc*t + b3*(pi/4))
其中b1，b2是NRZ polar 编码，b3 是NRZ unipolar 编码。
最后的输出是个gray code constellation 8PSK。
不过总觉得这个pi/4的phase shifter有点不靠谱。各位
有什么好的建议？ |

If M is a finitely generated R-module, then we can extract
only a finite direct sum of cyclic summands as a summand of M.
也就是说如果M=, 那么我们只能把M表示成：

发帖数: 2024 | 10 Do you guys really believe that the following object could lift off from the
moon and dock back to the commanding module orbiting the moon in the late
1960s? From the Soviet Union technology at that time, it was highly possible
to send man orbiting around the earth.
I am not saying that there was no such possibilities, but it is such a
tremendous task even by current technology standard? Welcome your comments. |

发帖数: 2024 | 11 When the rocket exploded without taking off, it would cause a disaster. In
previous USSR, one of the Blizzard exploded and killed over 20 excellent
rocket scientists and generals in charge of the launch, and it was a huge
setback for the USSR's space program.
Anyway, I would say the Saturn V rockets are huge and very powerful for the
Apollo project and a paradigm of its kind. While I am still not convinced how
they could lift off from the moon with such a small landing module.

modulator没必要管ground，但是要把电源线负极换个地方取取，不要接在radio外壳，要从radio

如果跟MP3没关系，那跟RCA口就没关系，RCA ground loop isolator对你没用。

发帖数: 572 | 29 Yes, installation cost is a big problem. It's not like module, you can
reduce cost by economy of scale. That's why I always suspect that solar
panel cannot achieve grid parity at the end. I do not have a specific number
for installation cost. I roughtly remember it's still larger than $2/W.
Anybody have the data of the current installation cost ? |

发帖数: 572 | 30 this should be be the overall cost. I searched google, the installation
is close to $2. At 2007, the module cost may be $4-$5. Adding up other costs
