METHOD AND APPARATUS FOR DC RESTORATION USING FEEDBACK |
摘要 |
A feedback circuit for restoration of DC in electrical signals is presented. A sample pulse representing a DC portion of an electrical signal is generated. The sample pulse triggers a sample and hold circuit to acquire the correct offset voltage in the electrical signal during this DC portion. The offset voltage feeds back through a summing node to the electrical signal thereby restoring the video signal to the desired DC voltage level with respect to ground.
