17. BTSC STEREO/SAP/DBX-DECODER and AUDIO PROCESSOR TDA9855
The TDA9855 is a BTSC stereo/SAP/dbx decoder and audio processor. It performs all functions to transform the composite baseband
signal into the appropriate audio output signals to line out and to the loudspeaker output stages.

TDA8840/8842/8844:
The TDA884X is IýC-bus controlled single chip TV processor which is intended to be applied in PAL, NTSC, PAL/NTSC and
multi-standard television receivers. These IC s are nearly pin compatible with the TDA837X TV processors but have a higher
degree of integration because the delay line (TDA4665 function) and the SECAM decoder have been integrated. In addition to
these functions some additional features have been added like Continuous Cathode Calibration (2-point black current loop
which results in an accurate biasing of the 3 guns), adjustable luminance delay time, blue stretching and dynamic skin tone control.
