Question: What is the primary focus of the performance requirement in receiver testing, distinct from a hardware-focused approach?
Option 1: Receiver's signal processing capabilities under specific channel conditions.
Option 2: Transmitter's ability to handle multiple frequency bands simultaneously.
Option 3: Antenna's efficiency in high-speed mobile scenarios.
Option 4: Baseband processor's computational throughput.
Explanation: This question requires understanding of telecom testing methodologies, specifically the distinction between hardware and software/signal processing aspects. The correct answer highlights the focus on how well the receiver can process signals in a defined scenario (e.g., high-speed train channel), crucial for ensuring reliable communication in varying environmental conditions, aligning with real-world telecom challenges like maintaining service quality in moving vehicles.
