METHOD FOR DISPLAYING AUDIO SOUND LEVELS ON TV SCREEN

摘要

a first A/D converter (10) converting the inputted analog audio signal into the digital signal; an audio signal processing section (20) converting the digital converted signal into the signal of analog left-right channel; a band pass filter (30) passing only the signal of fixed band; a second A/D converter (40) converting the audio signal of the fixed band into the digital signal; a section (50) separating the synchronizing signal by inputting the analog video signal; a detector (60) outputting the synchronizing signal detected from the separator; a microprocessor (70) controlling the system according to the key data; a character signal generator (80) generating the R,G,G signal.
