En "fruktstege"

Det var ju en kul idé att förbättra ljudkvaliteten genom att man använder tre olika nivåer på utgången... etta, nolla, och "inget"...Andy skrev:Den här är också intressant även om den startades 2001 : http://www.romanblack.com/picsound.htm
RomanBlack's BTc 1bit sound encoding skrev:Playback.
The new bit is read from the BTc sound data. It is compared with the last bit. If the 2 bits are the same the new bit is output on the digital output pin. If the new bit is different from the last bit the digital output pin goes high-impedance (disconnects). The resistor value is R.
The result is that for two successive 1 bits the cap voltage rises, and for two successive 0 bits the cap voltage falls. But where the bits are fluctuating the cap voltage stays the same, causing (in theory) less output ripple and a better playback quality.
