Transistor Testing Circuit: In-Circuit Testing - A quick test to check if a transistor is operational can be performed while the device is still connected in a circuit. Consider Fig.…
Traction Drive Rating and Energy Consumption: Traction Drive Rating and Energy Consumption - The speed-time curve of Fig. I0.6(a) is reproduced in Fig. 10.9. For simplification in calculations, it is…
Self Controlled Synchronous Motor Drive: A Self Controlled Synchronous Motor Drive employing a load commutated thyristor inverter is shown in Fig. 7.10. In large power drives wound field synchronous motor…
Color Picture Tube Working: A Color Picture Tube Working requires correct sweep currents, input voltages and drive voltages. Having said this very quickly, it is now a good idea to…
Vertical Deflection Circuit in TV: The Vertical Deflection Circuit in TV include the vertical oscillator and amplifier for vertical scanning at 60 Hz and a similar horizontal arrangement for scanning…
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…
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…
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.…
