Abstract

A television receiver includes a tuner stage, a selective filter stage connected to the tuner stage, and a intermediate-frequency stage connected to the selective filter stage. A field-strength-detection stage is also provided, which generates a field strength signal proportional to the field strength of the received signal. The selective filter stage includes a transfer function that is modifiable by a control signal derived from the field strength signal.
