Power spectrum for binary NRZ data with less than 50 percent transitions
Abstract
Spacecrafttoground telemetry received by the DSN can often be modelled as binary NRZ data with independent transitions of probability p equal to or less than 1/2. A simple expression is derived for the power spectrum of this type of data modulation; this formula is used to investigate how rapidly the data bandwidth decreases as p gets smaller.
