个box每月还有租费。有人直接用电视接而不用digtal box的吗？ 谢谢 |

在Amazon买的CD,按说70年代初的录音质量应该很好了啊.Anyway,手头另一张violin四
季(Pinnock1982)录音质量要好很多.难道录音技术革新这么快?不都是号称digtal

结果收到4封邮件后，现在再也没收到最后一封了。看了这4封邮件，有3封属于第一个
order，1封属于第2个order。也就是说第一单的4张gc有一张还没有发给我
给paypal digtal 发了信，没回应。是不是得开ebay case啊？ paypal流氓不会给吞了
吧？
撸了半天，花了250刀买了240刀的东西，还跑半天去mall里看小儿眼色，等要回来了还
得再去跑一趟
one more thing：今天店里的小二一听我要买240刀的egc，先发短信给manager，说100
以上的都要问问manager要批准。不过后来还是顺利批准买了。是不是风向收紧的信号

the A mount, with a flange focal distance 44.5 mm. ... The mount is now used
by Sony, who bought the SLR camera division from Konica Minolta, Konica and
Minolta having merged a few years before.

BYW, 用MATLAB反卷积deconv能计算，但不知结果对不对，有时好像有误差，
如果先用fft计算频谱，在ifft算时域结果，好像和直接deconv的结果不同。。 |

发帖数: 313 | 18 If we want to design a RF module (transceiver), do we have to use ADC?
Is there some method to directly send digtal signal?
Thanks a lot |
