Electronic Video Systems: Diagnostics and Maintenance 1. udgave

This practical, down-to-earth introduction to video systems begins with the most obvious difference between radio and television?the picture tube?and proceeds through computer monitors, VCRs, camcorders, cable TV, and high-definition television (HDTV). The author identifies the components of each system, then explains how each component contributes to the system's overall operation. Through this building-block presentation, readers learn current solid-state and LSI circuitry, as well as how to apply that basic knowledge to the circuits and systems they will encounter in the future. Coverage reflects NTSC standards, and compares them to such systems as PAL and SECAM, to give readers the background needed to understand all of the various global systems now in use. The full spectrum of the information about a component is contained in a single, comprehensive chapter that first defines what is required from that component, then explores how it is accomplished in current products, and, finally, explains why the component is used as it is. Computer monitors are discussed alongside television receivers to more clearly identify their similarities and differences.
