Abstract
A network for combining a switchable and variable tuning voltage with an AFC voltage so as to effect a change in the tuning control voltage at a tuner's tuning control terminal is disclosed. The network compensates for time delays associated with the AFC time-constant in a manner such that the tuning control voltage responds in proportion to and substantially instantaneously with changes in the tuning voltage. The compensation reduces the probability of AFC false-locking phenomena when, for example, switching from one channel of a television receiver to another.
