What does the term sample rate mean?
A sampling rate is a term that is used in digital recording to describe how much, and how often, data is used. In digital audio (sound recording), a new sample of analog data -- a new speaker position -- is sent out to the speaker quite often, usually at a sample rate of 44100 Samples/second. So when the music is recorded for a CD, a new sample is collected from the microphones just as often, usually at a sample rate of 44,100 Samples/second. A biologist may measure the temperature of a lake once a week. That temperature data has a sampling rate is 1 Sample/week. Sampling rate is independent of "channels" or "bit resolution". A highly instrumented concert may have a dozen channels, each one from a microphone sampled at 44100 Samples/second, but the total sampling rate is still 44,100 Samples/second.
As the temperature of a radioactive sample increases the rate of the nuclear decay?
The rate of nuclear decay increases as the temperature of a radioactive sample increases. This is due to the increased kinetic energy of the nuclei at higher temperatures, which facilitates interactions that lead to nuclear decay.
How you can Find the maximum data rate of a noiseless 4-kHz channel-using Analog encoding eg QPSK with 2 bits per sample?
for 4KHz then for noisy channel using Shannon theorem, sampling rate will be 8K samples/sec. So with 2 bit encoding, 2 bits are sent per sample. So the data rates is 8000 samples / sec * 2 bits = 16000bits / sec = 16kbps.
What are the factor affecting rate of penetration?
Rock type, porosity, and strength Bottomhole and bit-face cleaning and differential pressure at bit-rock interface Bit diameter, type, condition, and jet configuration Weight on bit and rotary speed
Name 2 things you could do to a sample of radioactive material to reduce the counting rate on a geiger counter?
1. put it in a lead box 2. move it further away
What is the bit rate a sample rate of a CD?
16/44.1
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 considered to be a high bit rate in a WAV file?
Unlike MP3 and WMA files, WAV files are not compressed, so they are not rated by bit rate (Mb/s). They are rated by sample rate, in samples per second. A high sample rate would be 96 kHz or 192 kHz. CDs have a sample rate of 44.1 kHz. In uncompressed audio, there is also the matter of bit depth, or resolution of the recording. CDs are 16-bit, but WAV files can be 24-bit or 32-bit.
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.
What bit-rate would you choose for ripping an mp3 from a CD?
320 kbps
What is relationship between sample rate and bit depth?
Please see attached links.
How do you find out what kbps you are set to when recording music?
In most recording programs, you are not recording directly to a compressed format (ie. one that describes the bit rate in kbps). Most are recording tracks in WAV or AIFF format, and each program has a method of setting the bit depth (16 or 24 bit) and sample rate (44.1 to 192 kHz). The compression to MP3, AAC, FLAC, OGG or other compressed formats happens after the recording, and you can choose the bit rate then. The calculation for kbps for CD quality (44.1 khz, 16 bit) is about 1411 kbps.
What sampling rate from a sound card would you require if you want to be able to record CD sound quality?
The standard CD is two-channel 16-bit PCM encoding at a 44.1 kHz sampling rate per channel.

How does differential pulse code modulation lower the bit rate of transmitted signals?
It signals the difference between successive sample sizes
What CD is better jonasbrothers CD jonasbrothers a little bit longer CD?
jonasbrothers not a little bit longer
What is sampling rate in sound?
The sampling rate is the number of samples taken from a continuous signal over a period of time (typically measured per second - Sa/s or Samples per Second). The Nyquist - Shannon Sample Theorem states that a sample rate should be double the highest recorded frequency. Since the range of human hearing is 20Hz - 20,000 Hz, the minimum sample rate should be 40,000 Hz. CD format sample rates are 44.1kHz for this reason as well as other technical reasons.
