It is a rounding error between the analog input voltage to the ADC and the output digitized value. Poster rated this answer 0 Votes. Oversampled PCM therefore exchanges fewer bits per sample for more samples in order to obtain the same resolution. Adding one bit doubles the resolution, adding two quadruples it and so on.

Message 6 of 7. Archived from the original PDF on 8 November Auto-suggest helps you quickly narrow down your search results audko suggesting possible matches as you type. The noise is nonlinear and signal-dependent.

In either case, the precision of each operation is determined by the precision of the hardware operations used to perform wudio step of the processing and not the resolution of the input data. The resolution of binary integers increases exponentially as the word length increases.
Oversampling a signal results in equal quantization noise per unit of bandwidth at all frequencies and a dynamic range that improves with only the square root of the oversampling ratio. Message 3 of 7.

Register Sign In Help. Retrieved 10 August Adapt them to the particular audoo and needs of your religious group. In basic implementations, variations in bit depth primarily affect the noise level from quantization error —thus the signal-to-noise ratio SNR and dynamic range.
From Wikipedia, the free encyclopedia. This question was closed by the author 0 Votes. This reduces the risk of clipping without encountering quantization errors at low volumes.

If the signal’s dynamic range is lower than that allowed by the bit depth, the recording has headroom. Views Read Edit View history.
Even more important was the realisation that there is a right sort of random noise to audjo, and that when the right dither is used, the resolution of the digital system becomes infinite.
Dynamic Range —60dB input, A-weighted: Retrieved 16 August Retrieved 13 September Because quantization error is assumed to be uniformly distributed with frequency, much of the quantization error is shifted to ultrasonic frequencies, and can be removed by the digital to analog converter during playback.
Message 1 of 7. For example, the Motorola DSP chip uses bit word sizes, bit multipliers and bit accumulators to perform multiply-accumulate operations on two bit mb9331 without overflow or rounding.
Archived from the original PDF on 7 April So your bit DAC is actually only ever going to be able to output at most bits of useful data and the other bits will be masked by circuit noise.
