Quizplus · Accepted Answer

In a typical radio receiver, the block labeled with a "?" usually represents the Intermediate Frequency (IF) amplifier. The IF amplifier is crucial for amplifying the intermediate frequency signal (which is the result of mixing the received signal with a local oscillator signal) before it is sent to the detector for demodulation.
