Television had its beginnings with:development in the 1920's and broadcasting beginning in the 1940's.Vertical resolution for U.S. NTSC television is approximately:339 horizontal lines.The device that feeds both visual and aural TV transmitter signals to the antenna while not allowing either to be fed back into the other transmitter is called:a diplexerA faulty TV receiver having symptoms of normal sound but no raster must have a problem in the:horizontal or vertical oscillator or high voltage power supply.Horizontal resolution for U.S. television is approximately:428 vertical lines.The color burst frequency for U.S. NTSC television broadcasts is approximately:3.58 MHzThe aspect ratio for NTSC broadcast television is:a 4:3 ratioThe most widely used TV camera imaging device today is:the CCDThe interval of time it takes the moving electron beam to move from the end of one line back to the start of the next lower line is known as:retrace intervalA faulty TV receiver having symptoms of no picture, no sound, and no raster must have a problem in the:main power supplyThe purpose of the PSIP is to (select one).it is used to identify the channelThe term for when a digital picture freezes even when there is motion is:pixelateThis is used by the digital receiver to lock onto the digital data stream so the multiplexed data can be recovered.the DTV pilot signalWhat three things make up the ATSC transport stream?PSIP, program, Information, control, ectThe field frequency for U.S. NTSC television broadcasts is:60 fields per second.The video compression technique selected for DTV transmission is:MPEG2The point where there is a lot of multiple echo and you have reached the threshold of visibility in a DTV signal is calledthe cliff effectMost television IF amplifiers are stagger tuned in order to:get a wide enough bandwidth for the TV channel but still have steep roll-offs at the passband edgesThe horizontal oscillator frequency for U.S. NTSC television broadcasts is set at approximately:15.75 KHzTo obtain the steep attenuation curve for the sound carrier portion of the IF signal passed by the TV receiver IF amplifiers, what is used?wave trapsThe RF modulation technique for ATSC DTV transmission is:8VSB
