DEVICE FOR AUTOMATIC COMPENSATING OF ACTIVE INTERFERENCE

摘要

The device is used in super-heterodyne receivers. It has improved noise protection and is simplified, which is achieved by an automatic compensator, the additional channel of which is formed by the main channel with frequency separation. In the device the additional channel is connected in parallel to the basic one and consists of a mixer (2) and a filter for intermediate frequency (5) and the input for the reference signal of the mixer (2) is connected to the local heterodyne through a frequency manipulator (3).
