Question 8-19C4
Element 8 (RADAR)What section of the receiving system sends signals to the display system?
Explanation
In a receiving system, the video amplifier is specifically designed to amplify the demodulated video signal. This amplified video signal contains the visual information necessary for a display system, such as a screen or monitor, to generate images. Therefore, the video amplifier sends its output directly to the display.
An audio amplifier processes audio signals for speakers or headphones, not visual displays. The I.F. (Intermediate Frequency) amplifier stage processes the signal before it's demodulated into baseband audio or video, making it an internal stage, not the final output to a display. A resolver is a type of sensor used for angular position detection and is unrelated to sending signals to a display in a typical radio receiver.
