Color TV Transmission: Having discussed the manner of indicating luminance and the two components of chrominance in Color TV Transmission, it is now necessary to investigate how they may be,…
TV Receiver Synchronizing Circuits: The task of the TV Receiver Synchronizing Circuits is to process received information, in such a way as to ensure that the vertical and horizontal oscillators…
Monochrome Television Receiver Block Diagram: Monochrome Television Receiver Block Diagram as shown in Figure 17-9, TV receivers use the superheterodyne principle. There is extensive pulse circuitry, to ensure that the…
TV Video Waveform: Blanking - TV Video Waveform voltage is limited to certain amplitude limits. Thus, for example, the white level corresponds to 12.5 percent (±2.5 percent) modulation of the…
Sawtooth Waveform in Beam Scanning: As previously discussed, one complete frame of a TV picture is scanned 30 times per second, in a manner very similar to reading this page.…
Moving Target Indicator Radar Block Diagram: Basically, the Moving Target Indicator Radar Block Diagram compares a set of received echoes with those received during the previous sweep. Those echoes whose…
Antenna Tracking System: Having acquired a target through a scanning method as just described, it may then be necessary to locate it very accurately, perhaps in order to bring weapons…
Microwave Link in Electronic Communication: A Microwave Link in Electronic Communication performs the same functions as a copper or optic fiber cable, but in a different manner, by using point-to-point…
