Certain aspects relate to providing an at least one audio source to at least one user. Application to testing bare or packaged electronic components. The result is significant cost savings in terms of time spent inputting entitlement constraint data by contract analysts as well as minimizing errors by those analysts who would otherwise be required to have a very high level of expertise in the software offerings while potentially inputting the same constraint data repeated times. It also receives circuit data from an internal bus and transmits the data received from the internal bus on to the TDM communications network. The gate dielectric film contains an addition element to prevent diffusion of oxygen. The predictive calculation unit outputs a component signal or a transformed component signal based on the predictive tap and the predictive coefficient.
