A class of de-free codes with minimum distance 4 which offer very simp
le encoding and decoding procedures is presented. Spectral analysis sh
ows that in addition to being de-free they offer strong spectral suppr
ession at low frequencies. A comparison with similar codes in the lite
rature shows that they provide a good compromise solution to the desig
n of practically realizable, high-rate, de-free error-correcting codes
with strong low frequency suppression.
