Abstract
Digital tuning systems are fast replacing the conventional mechanical systems in AM/FM and television receivers. The desirability of the digital approach is mainly due to the following operational features: *Precise tuning of station frequencies *Exact digital frequency display *Keyboard entry of desired frequency *Virtually unlimited station memory *Up/down scanning through the band *Station "search" (stop on next active station) *Power on to the last station *Easy option for time-of-day clock
