because human hearing is about 20kHz.

so according to sample theorem, it has to be twice..

What are the advantages and disadvantages of sampling a signal?

Sampling a signal is a process where some thing, usually an analog signal, is sampled at a particular frequency, and analysis and processing is performed on that sample stream. The advantages are that conversion between the time domain and the frequency domain using Fourier analysis is a very powerful technique that allows you to do a lot of different things, such as compression and filtering, without needing advanced electronics. You can also transmit the digital samples from one point to another, using digital electronics, rather than analog electronics. Disadvantages are that sampling, by its very nature, introduces distortion, because you have limited resolution on the ADC and you have limited frequency of sample rate. Often, however, you can do very well, so long as you understand the implications of sampling. One of them is called Nyquist Aliasing. That is where the sample rate is less than the Nyquist frequency of one half of the highest harmonic of the signal. This is a very noticeable distortion, perceived as a buzzing in inverse frequency terms, which must be properly filtered. In fact, if you look at a traditional audio CD, the sample rate is 44.1 KHz, making the Nyquist frequency 22.05 Khz. That is commonly above the range of human hearing, but you still must account for it, otherwise, the distortion could damage the equipment or degrade the signal quality.

What is the sampling rate in HZ of a music CD?

Standard audio CDs use a sample rate of 44.1 kHz, each sample has 16-bit resolution and there are two audio channels. 44,100 x 16 x 2 = 1,411,200 bits/s = 1,411 kbps. For comparison, the highest bit rate for MP3 is 320 kbps.


What is the difference between CD and DVD audio?

CDs play on two 16 bit 44.1 kHz channels and work on both DVD and CD players. DVD audio (DVD-A) requires a DVD player to work. It uses higher sample rates - up to 24 bit 192 kHz with stereo, but generally uses 24 bit 96 kHz - and can work on anything ranging from mono to 5.1 channels. That is not DVD-V. The difference is in terms of audio quality since the DVD-Audio format has 7 times more storage capacity then a regular CD-Audio. This means that you can actually hear the audio content on a DVD-Audio the best possible way ever since both the sample rate (192kHz) and the bit depth resolution (24bps) are higher then a regular CD-Audio (44.1kHz, 16bps) and would actually exceed the human hearing capability.

What is the roman numeral for 441?

Well, 441=400+40+1. Therefore, 441 would be CD (400, or 500-100) XL (40, or 50-10) I (1). That's CDXLI.


What is CD quality?

CD quality refers to the amount of detail saved to an audio file that would be typical of what you would find on a CD. This is measured in how often a change in the sound wave is detected, known as the sample rate, and to what level of detail this change is measured to, known as the bit depth.Sample rate is measured in kilo-hertz (kHz), or thousand samples per second. For CDs this 44.1kHz.Bit depth is measured in bits, which is the number of binary digets each sample uses. For CDs this is 16bit.
