From Audio belowThe Digital Adaptive Telephone Hybrid (DATH) provides a major advance in telecom to studio interfaces employing the latest digital signal processing techniques to give an adjustment-free connection between the audio mixer and telephone lines from the "on the spot" reporters and contributors to "phone-in" programmes.Isolating studio audio from the received speech during broadcast "phone-ins" has long presented difficulties for the studio engineer. Although analogue solutions exist, advances in silicon technology now permit an economic design using digital techniques.Using industry standard DSP circuits, significant improvements have been made in side tone rejection and delayed echo cancellation compared with the performance of conventional analogue devices.In the Digital Adaptive Telephone Hybrid (DATH) advanced Digital Signal Processing is used to implement a 256 tap adaptive Finite Impulse Response (FIR) Filter. This, together with an electronic hybrid having an optimised fixed balance impedance, splits the bi-directional telephone line signals into separate send and receive paths. Sidetone, the inherent leakage from the send to receive path, is minimised as the adaptive filter coefficients converge to values appropriate to the particular telephone connection. To meet the requirements of users the product can be interfaced with straight digital hybrids where interfaces to the users are handled by existing or specialised control panels, alternatively Audix Broadcast can supply modular based panels or sub assemblies where full remote control of the digital hybrid is possible. The interfaces show telephone line and hybrid status, interfaces and interlocks with telephone handsets as well as studio interfaces.
