Which action would primarily relate to reducing telemetry latency due to processing time?

• A. Reducing sampling delay
• B. Decreasing the queue length at ground station
• C. Increasing path loss to reduce signal quality
• D. Reducing coding complexity

Answer: (C)

Latency that comes from processing time refers to how long the system spends on encoding, decoding, and performing error checking on the data. If you reduce coding complexity, the encoder and decoder have fewer operations to perform per bit, which lowers the number of CPU cycles needed and shortens the overall processing time. That direct reduction in computation translates into a faster path from data creation to ready-for-transmission or interpretation, addressing the specific latency component tied to processing.

The other ideas affect different parts of the pipeline: sampling delay changes when data is captured rather than how long processing takes; queue length affects how long items wait in buffers, not the actual processing time; and changing path loss alters link quality and can lead to more retransmissions or lower throughput, typically increasing latency rather than decreasing it.
