In a single sideband receiver, what is the position of the intermediate frequency amplifier?

• A. Between the mixer and output
• B. Between the filter and product detector
• C. After the audio frequency amplifier
• D. Before the antenna

Answer: (B)

In a single sideband (SSB) receiver, the intermediate frequency (IF) amplifier is positioned between the filter and the product detector. This arrangement is essential for the proper functioning of the receiver, as the IF amplifier is designed to enhance the signal strength of a specific frequency before it is demodulated by the product detector. The product detector is responsible for extracting the audio signal from the modulated IF signal, and the filter preceding it ensures that only the desired signals pass through, minimizing interference from other frequencies. The IF amplifier boosts the filtered signal, which allows for better performance in terms of signal-to-noise ratio and overall clarity of the received audio. This positioning is crucial because it allows for precise tuning and amplifying of the desired signal while filtering out unwanted frequencies, leading to improved reception quality in a single sideband transmission.
