What is another term used interchangeably with demodulation?

• A. Demodulation
• B. High-pass
• C. Detection
• D. Tuning Circuit

Answer: (C)

Demodulation and detection refer to the same job: recovering the original information from the carrier. In a receiver, the detector stage pulls out the modulating signal from the modulated wave, so this process is commonly called detection. For AM, an envelope detector is a classic example of this, while FM uses a discriminator or other detector to recover the frequency changes that carry the information. The other terms describe filtering or tuning functions, not the actual information recovery.
