What are audio sampling signals and what is the required minimum sampling rate?

AI Thread Summary
Audio sampling signals refer to the process of converting analog audio signals into digital data by measuring the signal's voltage at specific intervals. The minimum sampling rate required to accurately capture the audible frequency range is typically at least twice the highest frequency of interest, following the Nyquist theorem. For example, to capture sounds up to 30 kHz, a sampling rate of at least 60 kHz is recommended. The discussion highlights a common confusion between the terms "audio sampling" and "audio sampling signals." Understanding these concepts is crucial for effective digital audio transmission.

Hi,

I have a question and I was wondering whether you might help me, because I have done a lot of research nut no clues. Just bits and pieces.

Thanks ALOT

Homework Statement



In digital transmission, what are audio sampling signals? What is the mimimum sampling rate required.

Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
"Audio sampling" is converting an analog audio signal into digital data by measuring the signal level (voltage) frequently enough to capture the shape of the signal wave. The frequency range audible to the human ear is the major consideration. If you want to get 30 kHz sounds in your digital file, you must measure at a rate of at least 30 000 times a second (likely twice that for technical reasons). Check

for details.

Hi thanks for the reply, I understand that. But what is "Audio sampling signals"? Not Audio sampling
 
Give me some help here please.
 
Sorry, I have not heard the term "audio sampling signals" before.
I thought you were asking for help with sampling OF audio signals.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
