*Question E2C12:
What indicates the delay between a control operator action and the corresponding change in the transmitted signal?*  

*Correct Answer is  C: Latency*  

### AI Response: (may contain errors)  

The correct answer to the question about the delay between a control operator action and the corresponding change in the transmitted signal is **C: Latency**.

### Explanation of the Correct Answer:
- **Latency** refers to the time delay from when a command is initiated by the operator until the effect of that command is observed in the transmitted signal. This can be caused by various factors, including processing time in the equipment and transmission delays.

### Why the Other Choices are Incorrect:
- **A: Jitter**  
  - Jitter refers to the variability in time delay in the transmission of packets over a network. It is not specifically about the delay from an operator's action but rather the inconsistency in signal timing.

- **B: Hang time**  
  - Hang time is not a standard term in radio communications. It may refer to a delay in certain contexts, but it does not specifically describe the operator's action delay in signal transmission.

- **D: Anti-VOX**  
  - Anti-VOX (Voice Operated Transmission) is a feature that prevents the transmitter from activating until a certain audio level is reached. It does not relate to the delay caused by operator actions but rather to the control of transmission based on audio input.

### Summary:
- **Latency** is the correct term for the delay between an operator's action and the change in the transmitted signal. Understanding latency is crucial for effective communication in amateur radio, as it can affect the timing of transmissions and responses.
