Silicon TV tuners poised to replace cans
Oct 1, 2005
By Alvin Wong and Jordan Du Val While the evolution of TV receivers has accelerated on many fronts in the last
decade, fully integrated silicon tuner design has lagged behind this evolutionary
wave. The silicon TV tuner is now perfected and will rapidly replace traditional
can tuners, just as transistors replaced vacuum tubes during the mid-1960s....
