Which of the following describes the output of the detector?

• A. Amplified RF signal
• B. Audio signal for the AF amplifier
• C. Unfiltered mixed signal
• D. Intermediate frequency output

Answer: (B)

The output of the detector is best described as the audio signal for the AF (Audio Frequency) amplifier. In the context of radio and communication systems, a detector's primary function is to demodulate a received signal, effectively extracting the audio information that was encoded onto the carrier wave. This extracted audio signal can then be sent to an audio frequency amplifier for further processing or amplification, allowing listeners to hear the transmitted audio content, such as voice or music. When a radio signal is received, it often consists of alternating current (AC) components at radio frequencies, which are not suitable for direct audio playback. The detector converts these RF signals into an audio frequency signal, which is then usable by audio processing circuits. This is crucial in radio communication, where the goal is to retrieve the original information from the modulated carrier wave. Other options refer to different signal states that do not accurately describe the output of a detector. For example, while an amplified RF signal may be part of the broader communication chain, it is not the final output of the detector. Similarly, an unfiltered mixed signal does not specify the demodulation into audio frequencies, and an intermediate frequency output pertains to stages of the receiving process before the final audio signal is generated. Therefore,
