小明的老婆要生了
他赶紧把她送到医院
在急诊室外等著
过了许久
医生才缓缓走了出来
“医生，请问一下…
100 gigabytes hard disk is used to store PCM video signals.
One volt peak-to-peak NTSC video signal is sampled as 10.73864MHz.
The quantizing scheme is selected so that peak-to- peak signal-to-quantizaction noise is at least 45 DB
(A) calculate the quantization levels and bits/sample required.
(B) what is the serial bit rate of the digital video signal and how many minutes of video program can the hard disk store?”
医生：“选a选b机率各50%，这样猜错别说你读清大”
