小明的老婆要生了
他趕緊把她送到醫院
在急診室外等著
過了許久
醫生才緩緩走了出來
「醫生，請問一下…
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?」
醫生：「選a選b機率各50%，這樣猜錯別說你讀清大」
