Although PMP Exam is not easy, but it's not as hard as most people have thought. I've studied it for about a month; roughly spend about 2 hours average during 4 weekdays, increase to 3 to 4 hours toward the last two weeks, and full time study on the two weekends before taking the exam.  Using Rita's and lot of practice exams questions, continue to try it until score about 80%.

May 2011 will be another great year for all of us. It's one of the year that I like just simply it contains the number 11 that I like. Today is 1/1/11, and I completely finished move to my small little new house. I've done a lot of things in 2010, although it wasn't an easy year, but with all the helps and supports from family and friends.. it became one of the most successful and enjoyable year I've ever had. Special thanks to all of you who stick together with me throughout this time.

Happy New Year!!

Hi blog and everyone..

Today I’m so tired by studying for the midterm since after got back from work. It's more three months I haven’t taken any exam. I'm pretty much only stepped out for my bedroom to have dinner.. other than that, I’ve been sitting in this back chair for a more than 6 hours.. will soon get to a point of don't know what I’m happened to read :) but good that it is not there yet.

Life with school and work full time is very challenge, but it is productive if you can handle it.

DO .....
always respect yourself.
always maintain your personal integrity.
always help someone else when you can.
always rely on your spiritual strength.
always set higher goals.
always meet deadlines.
always check your work.
always remember your primary goals.

Although i still remember to do all of the above., but I believe that I did so bad on one of my midterm last week.. either coz it's hard or coz I didn't pay enough attention to study the exam, i will still have to accept the result, and this makes me even more stressful after taking the exam.

Sampling:
-To get a good representation of sound in digital format, we need to sample its amplitude at a rate (sample per second, smp/s) equal to at least twice the max frequency (in Hz) of the analog signal.
-After sampling, the signal amplitudes must be put in digital form---this process call quantization. 8 bits per sample are usually used for telephone voice, and 16 bits per sample for each channel for stereophonic compact disc.
Level of amplitude can be distinguished: 2^8 = 256 or 2^16 = 65536
Digital data in bits = 4000 *2 *8bit/sample = 64,000 bps
Compact disc = 44,100 *2*16 =1.41 Mbps
