Question 8-31D3
Element 8 (RADAR)Which of the following functions is not affected by the timing circuit?
Explanation
A resolver is an electromechanical transducer that generates analog electrical signals proportional to the angular position of its rotor. Its output represents a physical angle and is inherent to its design and rotation, not directly affected by the timing of electronic pulses or sweeps within a system.
Conversely, pulse repetition frequency (PRF) is the rate at which pulses are generated, a direct function of a timing circuit. Sweep drive, such as in an oscilloscope or radar display, controls the rate and duration of the electron beam's movement, which is precisely set by timing circuits. Modulation often involves varying a carrier signal, and the *timing* of these variations or the generation of modulating pulses (e.g., in pulse modulation) are critically dependent on timing circuits.
