what is pcm Informational
- Sharing a single transmission medium by interleaving samples from multiple channels
- Number of bits per sample
- Signal generators, spectrum analyzers, audio analyzers
- Avoiding aliasing and ensuring sufficient data points How does PCM relate to the fundamental limits of data transmission rate over a noisy channel, as described by Shannon's channel capacity theorem?
- Dynamically adjusting the step size based on the slope of the input signal
- Using recorded sounds vs. generating waveforms mathematically
- Basis for digital image and video processing What are the trade-offs between the complexity of a PCM system and its performance in terms of fidelity and bandwidth?
- Removing high-frequency artifacts introduced by the sampling process
- Understanding the noise characteristics What are the implications of non-ideal characteristics of the sampling clock (e.g., jitter, phase noise) on the accuracy of the PCM representation?
- Selecting appropriate sampling rates and bit depths based on the frequency content and amplitude range of the signals
