G8B02
What is the term for interference from a signal at twice the IF frequency from the desired signal?
Pick an answer to check it.
Answer: B. Image response
An image is an unwanted signal located twice the IF away from the desired signal, on the other side of the local oscillator. It also mixes down to the IF, causing image response.
Tip: Image sits 2 x IF away.
