Computers record music by changing sound waves into signals that the computers can store. They then decode these signals to reproduce the music that the signal represents. Analog recordings accomplist this with a signal that is continually changing This signal is a re-creation of the sound wave of the musiC. Digital recordings are samples of the music that computers store as a series of numbers. This creates a type of square wave. Later, computers decode these numbers to reproduce the recorded sound. A student claims that digital signals create more reliable recordings of music than analog signals do. Which statement supports this claim? A. Computers encode digital signals, which makes them more secure. B. Digital recordings take more samples every second than analog recordings do. C.

Answer 1

### D. Digital recordings contain fewer errors because computers store the music as a series of numbers.

Answer 2

## Step 1: Identify the Claim ### The claim is that digital signals create more reliable recordings of music than analog signals do. ## Step 2: Evaluate Each Option ### - **Option A:** Talks about encoding and security, not reliability specific to sound quality. - **Option B:** States that digital recordings take more samples but doesn't directly imply reliability. - **Option C:** Incorrectly states that digital recordings are exact replicas, which they are not. - **Option D:** States that digital recordings contain fewer errors because they are stored as numbers, directly supporting the claim of reliability. ## Step 3: Select the Correct Support Statement ### Based on the evaluation, Option D is the statement that supports the student’s claim that digital signals create more reliable recordings of music.
