Abstract
Markov models and values of channel capacity are presented for multilevel sequences with the number of signal levels ranging from four to seven, subject to three classes of channel-input restrictions. Several new line codes suitable for use in digital communication systems are presented, together with their error propagation properties and power spectral densities. These codes satisfy restrictions regarding runlength and zero-frequency components.<>
