Abstract
A system and method for providing discrete analog voltage levels. The system and method employs a pseudo-random sequence generator for generating random-sequences of binary values, namely zeros and ones, based on a digital input. The pseudo-random sequence serves to modulate a current source whose output is integrated to develop a constant discrete analog voltage output. This method reduces spurious frequency interference on the circuit. The system and method can be employed in a node of a wireless ad-hoc communications network.
