Hello,
This is my first thread and I have a problem with demultiplexing the digital PCM audio data stream.
Recently I designed a discrete R-2R DAC using information from the I2S spec sheet and wiki,
but when i first tested it, the output wave is split in 2: upper part and lower part.
I later found out that the PCM stream is coded as a signed integer using the 2's compliment method
but the shift-register can only decode a unsigned integer.
My question is if theres anyway I could change the signed PCM stream into unsigned?
OR
Is there another way of decoding this PCM Stream?
Thanks,
Boris
