Digital Technology - CDs and Storage Space

AI Thread Summary
One minute of music on a CD requires approximately 10 MB of storage space based on a sampling rate of 44.1 kHz, a bit depth of 16 bits, and two channels. The confusion arises from the interpretation of bit depth; it refers to the number of bits used per sample, not a reduction to 4 bits. The calculation for storage space involves multiplying the sampling rate, bit depth, and number of channels. Clarification on terminology is essential, as bit depth is a standard term in digital audio. Understanding these concepts is crucial for accurate audio storage calculations.

Hi,

My teacher gave me the following information and asked me to prove that 1 minute of music requires 10 MB of storage space in a CD.

Sampling Rate: 44.1 kHz
Bit Depth: 16 bits
No. Channels: 2

I am a bit confused. If the bit depth is 16, that means I have 4 bits. But I only get the correct answer when I use 16 bits. Should instead of Bit depth it say number of bits?

Thanks,
Peter G.

In digital audio, bit depth describes the number of bits of information recorded for each sample.

Wikipedia, therefore unreliable.
 
Bit depth means number of bits.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
