3.Music search
Music search is constituted following .
1 Input signal reference level comparison
2 Music detection
3 No music detection
1 Input signal reference level comparison
Input signal reference level comparison is comstituted amplifier and level comarison.
When input signal is bigger than reference level,level comparison output the pulse
which added internal clock.
Input signal
Clock signal
pulse output
(after level detection)
reference
level
Then reference level can be changed ,thanks to the following internal R2 and
external R1 which determine the amplifier gain .
Lch
R2=50k
R1
Internal resistance
precision is about
±30%.
Level comparator
Gain Gv = (R1 + R2) / R1
