Attempting similar changes in an analog filter would require component changes and potentially a new circuit layout.

The flexibility of digital filtering provides a particular advantage to digital equalization. Because of its programmability,

a single design using digital filtering can provide a wide range of filtering functions. As a result, this one design can

span a number of applications.

For a product that is in production, digital filtering can permit equalization changes with minimal cost impact because

of this programmability.

One concern about digital filters is that some implementations have been prone to zero-input limit cycles. This is a

condition where the filter oscillates at a low level when no signal is presented. In a digital audio system, this condition

may present itself as a tone or low-level noise. The TAS3001 has a patent-pending technique to combat this problem.
