Final answer:
Digitizing sound involves converting analog signals into digital form and can be done with different levels of quality and compression methods, including MPEG. While perfection isn't possible due to practical limitations, the digitization of sound can represent a wide range of values. Lossless and lossy compression techniques are used depending on the use case.
Step-by-step explanation:
The process of digitizing sound involves converting analog waveforms into a digital format that can be processed, stored, and reproduced by electronic devices. While perfection in digitization can never truly be achieved due to limitations in resolution (number of bits) and potential compression artifacts, the process is quite sophisticated. Among the options provided:
- Digitizing sound does not achieve perfection using an unlimited number of bits, as an unlimited number does not exist in a practical sense, and there are always some quantization errors.
- Digitization can be accomplished via compression methods including MPEG, which can encode audio using lossy compression to reduce file size while retaining a high level of audio fidelity.
- When signals are digitized, the binary system uses bits to represent a wide range of values, including both positive and negative values.
- Digitizing sound does not require lossless compression techniques, as both lossy and lossless compression can be used depending on the requirements for quality and file size.
Lossless compression is a method of data compression that allows the original data to be perfectly reconstructed from the compressed data, while lossy compression allows for some loss of data, which may not be perfectly restored in the decompression process.
