Single Phase Induction Motors Working Principle: Single Phase Induction Motors Working Principle are inferior in performance and lager in weight and volume compared to three-phase motors of the same rating.…
Types of DC Motor: The commonly used Types of DC Motor are shown in Fig. 5.1. In a separately excited motor, the field and armature voltages can be controlled independent…
Monochrome Television Transmitter: As shown in the block diagram of Figure 17-2, a Monochrome Television Transmitter system is quite unlike any of the transmission systems studied previously. This section will…
CW Doppler Radar Block Diagram: A simple CW Doppler Radar Block Diagram, such as the one shown in Figure 16-14, sends out continuous sine waves rather than pulses. It uses…
Phased Array Radars: Phased Array Radars - Introduction With some notable exceptions, the vast majority of radars have to cover an area in searching and/or tracking, rather than always being…
Frequency Modulated Continuous Wave Radar: The greatest limitation of Doppler radar, i.e., its inability to measure range, may be overcome if the transmitted carrier is Frequency Modulated Continuous Wave Radar.…
Radar Beacons: A Radar Beacons is a small radar set consisting of a receiver, a separate transmitter and an antenna which is often omnidirectional. When another radar transmits a coded…
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…
