Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form of digital audio in computers, Compact Discs, digital telephony and other digital audio applications. In a PCM stream, the amplitude of the analog signal is sampled regularly at uniform intervals, and each sample is quantized to the nearest value within a range of digital steps.
Linear pulse-code modulation (LPCM) is a specific type of PCM where the quantization levels are linearly uniform. This is in contrast to PCM encodings where quantization levels vary as a function of amplitude (as with the A-law algorithm or the μ-law algorithm). Though PCM is a more general term, it is often used to describe data encoded as LPCM.
A PCM stream has two basic properties that determine the stream's fidelity to the original analog signal: the sampling rate, which is the number of times per second that samples are taken; and the bit depth, which determines the number of possible digital values that can be used to represent each sample.
http://www.fiberoptics4sale.com/wordpress/what-is-pulse-code-modulation-pcm/ http://www.fiberoptics4sale.com/wordpress/ In a brief sentence, pulse code modulation is a method used to convert an analog signal into a digital signal. So that it can be transmitted through a digital communication network, and then converted back into the original analog signal. The PCM process includes three steps: Sampling, Quantization, and Coding. In the sampling process, the magnitude of the analog signal is sampled regularly at uniform intervals. The obtained values are called samples. For a 4 kHz voice channel, the sampling rate is 8000 Hz, which means the signal is sampled 8000 times per second. The samples will then be converted to digital numbers as we will see in the quantization pro...

A short compilation of footage I shot from Winton Performance car mania 2014, Unfortunately i had to use my Still camera for some video as my Video camera has been damaged. that is why some footage struggles to focus at times. so I apologise
Let's play Pro cycling manager 2017... Road to the yellow jersey. Welcome to the first episode of my PCM 2017 pro cyclist career mode. Join me on my road to win the greatest bike race of all time... the Tour de France. I'm a massive cycling fan and thought I'd give this game a go. I used to play PCM alot a couple years ago and I think I'll have fun making vidoes for it.

Avoiding unnecessary replacements and warranty returns are important to professional technicians and consumers. Most problems resulting in warranty returns can be avoided by following the proper Before, During, and After installation procedures.
I heard you sing a rebel song,
sung it loud and all alone.
We can't afford the things you save,
we can't afford the warranty.
I see you walking in the glare
down the county road we share.
Our southern blood, my heresy,
damn that ol' confederacy.
It took a long time to
become the thing I am to you.
And you won't tear it apart
without a fight, without a heart.
I'm sorry for what you have learned,
when you feel the tables turn.
To run so hard in your race,
now you find who set the pace.
The landed aristocracy
exploiting all your enmity.
All your daddies fought in vain,
leave you with the mark of Cain.
It took a long time to
become the thing I am to you.
And you won't tear it apart
without a fight, without a heart.
It took a long time to
become you, become you.
The center holds, so they say.
It never held too well for me.
I won't stop short for common ground
that vilifies the trodden down.
The center held the bonded slave
for the sake of industry.
The center held the bloody hand
of the executioner man.
It took a long time to
become the thing I am to you.
And you won't tear it apart
without a fight, without a heart.
It took a long time to
