Q

Which of the following is true of SITOR (NBDP) in FEC mode, in the presence of static crashes.

🔍 Key Concepts

• SITOR (NBDP) FEC mode basic operation • How forward error correction (FEC) deals with noise like static crashes • Difference between ARQ (automatic repeat request) and FEC modes in telex systems

💭 Think About

• Think about what FEC is designed to do when there are brief bursts of interference: how does it try to protect each character? • Consider which option correctly describes a built‑in error‑protection feature, not something that depends on external conditions like propagation or manual requests. • Ask yourself: in FEC mode, what must the transmitter and receiver agree on ahead of time for the system to work at all?

✅ Before You Answer

• Verify which option mentions a method of adding redundancy to the transmission to combat errors. • Eliminate any choice that talks about behavior that depends on requests from the user/receiver, since FEC is a continuous process. • Check that the correct choice reflects a system where timing/synchronization is necessary, not absent.
