- Jul 24, 2018-

In a wireless system, an interfering carrier frequency may use a heterodyne tuning system to generate an identical intermediate frequency (IF) masquerading as a normal carrier frequency, although they are filtered before the frequency enters the system, but sometimes there will still be erroneous reception, which will cause the receiver to process it. The result is some unsatisfactory performance and interference (at least intermittent).
