Q

Unblanking pulses are produced by the timer circuit. Where are they sent?

🔍 Key Concepts

• Role of unblanking pulses in radar display systems • Function of the CRT (cathode-ray tube) and its beam control • How IF amplifiers, mixers, and discriminators process signals differently from display control

💭 Think About

• Ask yourself: Which component actually creates the visible trace or picture that the operator sees? • Which stage uses timing pulses to allow or stop the electron beam from drawing on the screen? • Are unblanking pulses used to process RF/IF signals or to control when the display is visible?

✅ Before You Answer

• Verify which block in a basic radar block diagram is directly associated with the screen/visual display. • Confirm that IF amplifiers, mixer, and discriminator are all involved in signal frequency/phase/amplitude processing, not in drawing the picture. • Identify which choice corresponds to the display device that needs to know when to show or hide the trace.
