摘要：A synchronizing pulse processor accepts integrated and differentiated
composite sync signal inputs of either positive or negative polarity. Processed horizontaland vertical sync pulses are produced which have a single predetermined polarityindependent of the polarity of the composite sync signal. The polarity of the
differentiated composite sync signal is used to select the reference level for the verticalsync pulse threshold detector. The sync processor may be formed as a part of anintegrated circuit and require only two input interface terminals regardless of compositesync signal polarity.
