Question: What is the primary purpose of measuring spurious response in a receiver?
Option 1: To evaluate the receiver's ability to transmit signals on multiple frequencies simultaneously.
Option 2: To assess the receiver's capability to receive a wanted signal without degradation due to unwanted CW interfering signals.
Option 3: To determine the receiver's sensitivity to changes in temperature and humidity.
Option 4: To test the receiver's compatibility with different types of antennas.
Explanation: Measuring spurious response is crucial in evaluating a receiver's ability to receive a wanted signal on its assigned channel frequency without excessive degradation caused by unwanted CW interfering signals at other frequencies. This ensures that the receiver can maintain its performance and provide reliable communication services even in the presence of interference.
