What is the signal path of the ETVS?

The signal path of the ETVS is accurately represented by the path that includes the card rack, transceiver, radio, and aircraft. This sequence illustrates the flow of information through the various components that facilitate communication between the system and the aircraft.

Starting with the card rack, which houses critical electronic components and connections, the signal is then sent to the transceiver. The transceiver plays an essential role in modulating and demodulating the signals for transmission and reception, ensuring that the communication is both effective and efficient. Following this, the radio transmits the signals to the aircraft, allowing for real-time communication and control. This sequence is fundamental to the operation of ETVS, as each component serves a specific purpose in converting data into a format suitable for the aircraft and vice versa.

The other options misrepresent the flow of the signal in the ETVS context. By not including the necessary transceiver or incorporating irrelevant elements like the ground station or flight center, they do not accurately capture how signals are transmitted and received in this specific system. Understanding this correct path is crucial for effective communication protocols and operational efficiency in the application of the ETVS.
