Pros and cons of NICAM vs DVB vs DAB (original design)

Disadvantages

NICAM
-- J.17 Emphasis curve
-- 32 kHz sample rate
-- 14 bits vs 16 bits of modern systems; requires resampling for 16
bit origin material
Still, if one were designing a DAB system in the mid-1980s ... NICAM
is near perfect.
-- IF AND ONLY IF "RDS" datastream is added

14 bits and 32Khz near perfect? Even CD players managed 16 bits 44.1
Khz in the mid 80s. You're also forgetting that NICAM has virtually
sod all error correction. The slightest dodgy signal and its off into
wax cylinder audio mode (though you won't here it on most TVs , they
mute or switch to the FM sound as soon as the bitstream goes wonky)


MP2 has no error correction either, you dummy, they add the error correction
prior to transmission.
