The (120) data bytes represent (60) 12-bit linear SP 1200 data words:

byte 0: 0bbbbbbb bbbbbbb = 7 ms bits of data word 0

byte 1: 0aaaaa00 aaaaa = 5 ls bits of data word 0

byte 2: 0ddddddd ddddddd = 7 ms bits of data word 1

byte 3: 0ccccc00 ccccc = 5 ls bits of data word 1

——etc———

byte 119: 0yyyyy00 yyyyyyy = 5 ls bits of data word 59

The 12-bit data is in “complement offset binary” format: most negative value = 000 hex,

“zero” = 800 hex, most positive = fff hex
