🔍 Key Concepts

• How a sweep (time-base) circuit works in radar/CRT displays • The role of deflection coils in moving the CRT (cathode ray tube) beam • Difference between video amplification and beam deflection in a radar display

💭 Think About

• Ask yourself: What does the word sweep refer to on a radar or CRT display – changing brightness, moving the beam across the screen, or something else? • Which component in a CRT actually causes the electron beam to move in a line or circle so that echoes can be painted on the screen? • Is it typical in electronics for one amplifier to handle all functions (power, deflection, and resolver), or are these usually handled by separate, specialized circuits?

✅ Before You Answer

• Be clear on the function of video amplifiers (what signal they work on and what they change). • Recall what the deflection system (coils or plates) in a CRT does to the electron beam. • Consider whether a resolver is directly involved in sweeping the CRT beam, or if it has a different purpose in the system.
