Question: What is the primary objective of measuring spurious response frequencies against a less stringent test requirement in a TDD (Time Division Duplex) receiver?
Option 1: To evaluate the receiver's ability to filter out high-level interference signals without compromising its sensitivity.
Option 2: To assess the transmitter's power amplification under various frequency conversion concepts.
Option 3: To determine the optimal frequency allocation for uplink and downlink channels in a TDD system.
Option 4: To test the receiver's switching speed between transmission and reception modes.
Explanation: This question requires understanding of telecom concepts, specifically receiver sensitivity and interference mitigation. The correct answer highlights the key aspect of measuring spurious response frequencies: ensuring the receiver can withstand high-level interference without degrading its sensitivity, crucial for maintaining overall network performance and user experience.
