In a microwave receiver, what is the function of the detector?

The function of the detector in a microwave receiver is to convert intermediate frequency (IF) pulses into video pulses. This is a crucial step in the signal processing chain of the receiver. Once the microwave signal has been down-converted to an intermediate frequency, the detector picks these IF pulses and demodulates them, producing video pulses that are more suitable for further processing, such as display or analysis.

Video pulses represent the amplitude variations of the original incoming signal, allowing the signal to be interpreted in terms of the information it carries, such as audio or video data. This conversion process is essential for translating the complex modulated signals received by the microwave receiver into formats that can be effectively utilized by other systems.

The other options pertain to different functionalities that do not align with the primary role of the detector. For instance, amplification refers to increasing the strength of a signal, generation of frequency signals relates to the creation of new frequencies, and controlling voltage levels pertains to voltage regulation rather than the direct conversion of signals. Each of these functions may be performed by different components within the microwave receiver, but they do not capture the specific role of the detector.
