Signal discriminating apparatus for extracting component signals from a composite signal

摘要

An apparatus for extracting a specific component signal from a composite signal composed of a first component signal and a second component signal. The apparatus includes two transistors which separate a received composite signal into two separate component signals by way of a sampling signal synchronized with the first or the second component signal of the composite signal, whereby the desired component signal can be selected. In the case of a color television system, the color burst signal can be extracted from the composite color signal.
