Which change would let a receiver handle a stronger adjacent-channel signal?
Answer: A
Adjacent-channel rejection is a filtering problem, so steeper skirts at the intermediate frequency are the remedy, usually achieved by cascading more ceramic filters. A quieter front end improves weak-signal sensitivity, which is a different complaint. De-emphasis and audio bandwidth act after detection and cannot separate channels. Matching the remedy to the interference geometry is the recurring discipline of receiver work.
