Power spectrum for binary NRZ data with less than 50 percent transitions
Abstract
Spacecraft-to-ground 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.
