A DSP only processes digital signals.

These digital signals are derived from generated from real-world analog signals. But what makes codecs superior from Analog Devices Ad18xx converters is that they are programmable.

The programming of a codec is done via its internal indirect registers. What does it consist of??

In the early Analog Devices Ad18xx of digital audio, the cost and size of system hardware needed to implement high-fidelity audio was not practical. These components added up to a larger, relatively expensive system. What ADI did not forsee is that many of the codecs such as the AD that were designed to target the computer audio market were being designed into DSP audio applications, or even for embedded control system applications.

It utilizes low-performange analog circuitry by shifting the burden to the digital CMOS Analog Devices Ad18xx. This method has become an attractive choice for moderate-cost dedicated audio applications.

Dynamic Specifications: These refer to the AC performance specifications. This is the ratio of the input signal S to the background noise N in a system. The ratio of the rootmean-square Analog Devices Ad18xx of a full-scale fundamental input signal to the rms sum of all other spectral components in the passband, expressed in decibles dB and percentage.

Quantization Error: All ADCs will have at least a minimum error as a result of the discrete or finite specs that represent the analog input, and this error is directly proportional to the resolution. Essentially, this is an Analog Devices Ad18xx of how far it is possible to go below the full-scale input signal without hitting noise or distortion.

This is usually measured from 0 to 20 kHz and is expressed in decibels dB. Dynamic range is measured with a dB input signal and is calculated as follows: Analog Devices Ad18xx harmonics are below the noise with a dB input, so the noise level establishes the dynamic range. Total Harmonic Distortion: A very important specification in audio systems, the THD is defined to be the RMS root-mean-square ratio of the sum of all spectral components harmonic distortion amplitudes to the original full-scale Analog Devices Ad18xx amplitude.

Passive Support Components: Codecs will end up depending on the passive components resistors and capacitors that Analog Devices Ad18xx them for accuracy and stability. The components should be chosen as recommended by the data sheet, or the codec perfomance can be severly affected.

Intermodulation Distortion IMD: These additional frequencies will consist of the sum and difference between the original input frequencies and their harmonics. Gain Error: This is also the full-scale error, and it refers to Analog Devices Ad18xx difference beween the input that produces a full-scale code and the ideal voltage, expressed in least significant bits.

This is also expresses as a percentage of the actual output to the expected output. Offset Error zero error: Midpoint between converter shresholds to Analog Devices Ad18xx ideal response in LSBs. Group Delay:
