if •* They talk of Pigeons and Glitch "Pigeons" are not birds to a Bell System technician. They are impulse noises causing spots which seem to fly across the TV picture. And when he talks of "glitch" with a fellow technician, he means a low frequency interference which appears as a narrow horizontal bar moving vertically through the picture. It is important that our technicians can describe the quality of their signals in terms which mean the same to Bell System technicians in television operating centers along the line. Thev continuallv check their monitors and oscilloscopes to guard the quality of the signal as it wings across the nation. If one of them notes any defect in the picture, he may want to compare the signal he is receiving with those received by monitors back along the line. It is important that they talk a uniform language with precise definitions. That way they quickly isolate the point of interference and correct it. This teamwork along Bell System lines is another item which assures the network that the signals represent the best possible service that Bell System ingenuity can provide.
