最近因為剛"又"換新工作(前一個工作只撐了3個月), 很討厭的是又要重新的熟悉環境, 一剛始來公司同期其實也有一個比我早2個禮拜來的新人(我們兩個其實也不算新人, 都是有工作經驗的), 但是另一個新人好像都跟大家都不錯, 我卻大家都不太想理我, 難道Design house大家都這麼獨立冷漠,也沒有迎新這回事..跟系統廠差好多...

Adjacent Channel Selectivity
Adjacent Channel Selectivity
This characteristic deals with stations immediately adjacent i.e.(200KHz away) that might intrude on the station you have tuned. If the tuner is equipped with switchable IF bandwidth, this position would be known as 'wide'. It offers the widest bandwidth through which the signal must pass through to be decoded. A typical level is 8dB. (higher number value = better).
Alternate Channel Selectivity
This characteristic deals with stations adjacent (400KHz away) that might intrude on the station you have tuned. If the tuner is equipped with a switchable IF bandwidth, this position would be known as 'wide'. A typical level is about 50dB. (higher number value = better).

TDMA Noise
TDMA (time-division multiple-access) time-slot sharing technique that results in high-power RF in the 800MHz to 900MHz or 1800MHz to 1900MHz bands.
The transmitter current, which can exceed 1A, pulses during a phone call at a repetition rate of 217Hz and pulse width of about 0.5ms.
If current pulses couple to the audio circuitry, the harmonic-rich 217Hz signal results in the audible buzz.

支持CMMB、DAB、T-DMB/DVB-T/DVB-H多款标准的移动数字电视接收芯片
摩威科技近日对外宣布，支持中国移动多媒体广播标准CMMB，数字音频广播标准DAB，以及国际移动电视标准T-DMB，DVB-T/DVB-H的MV2001G移动数字电视接收芯片将于近期投放市场。
看來也是SOC chip 而且重點又多了T-DMB，DVB-T/DVB-H 等數位電視的功能
應該是強勁的對手, 待後續觀察
