Digital Television Signal-Receiving Device with Signal Strength Showing Function

摘要

A digital television signal-receiving device with signal strength showing function is disclosed. The digital television signal-receiving device includes a tuner, a microprocessor control unit, and a signal strength indicator. The signal of digital television is tuned with the tuner. The microprocessor control unit could read a signal decibel value of the signal of digital television and provide a strength signal corresponding to the signal decibel value. The signal strength indicator driven with the microprocessor control unit could receive the strength signal and show an indication of the signal strength.
