High frequency circuit equalisation method for television tuner

摘要

The equalising takes place using desired electronic circuit features in which the physical values of the television (TV) tuner electronic components are changeable. The tuner comprises printed capacities and or inductances which are changeable with respect to their physical values, by a laser beam. The change is such that the TV tuner contains preset tolerance regions with respect to its electronic properties, so that the laser beam can carry out the changes of values of the capacities and/or inductances for each property in small steps, in the direction of an optimum, with the equalising stopped when the optimum is exceeded.
