Abstract
A digital error signal generator produces a pseudorandom bit sequence having a predetermined probability density. Selective multiple pseudorandom bit densities, each having a predetermined probability density, are obtained from a single original pseudorandom bit sequence. Multiple data channels are serviced simultaneously by a single error signal generator with the probability density being individually selective for each channel.
