The circuit that develops timing signals is called the:
  • Resolver.
  • Correct Answer
    Synchronizer.
  • Pulse forming network.
  • Video amplifier.

A synchronizer is a circuit used to align or synchronize different parts of a digital system by ensuring that data transfers occur at appropriate times. It helps manage the timing and coordination of various components within the system, allowing them to work together seamlessly.

Which of the following functions is not affected by the timing circuit?
  • Correct Answer
    Resolver output.
  • Pulse repetition frequency.
  • Sweep drive.
  • Modulation.

Which of the following functions is not affected by the timing circuit?

Resolver output.

A timing circuit is responsible for generating and controlling various timing signals in electronic systems. It ensures precise synchronization and coordination of different components. The timing circuit affects the timing of events but does not directly influence the "Resolver output."

A resolver is a type of rotary electrical transformer used to measure angular position. It converts an input mechanical angle into an electrical signal. The resolver output is dependent on the physical rotation of the input shaft and is not directly related to the timing circuit's operation.
