Abstract
A pseudorandom sequence generator including a first feedback shift register having at least one input and at least one output and a first controller having an output in communication with the at least one input of the first feedback shift register; the first feedback shift register operating at a first speed S,and the first controller operating at a second speed S,. In one embodiment the first speed S,of the first feedback shift register is an integer multiple of the second speed S,of the first controller. In another embodiment the first feedback shift register includes a shift register having an input, an output, and at least one tap; and a feedback function generator having a first input in communication with the at least one tap of the shift register, a second input in communication with the output of the first controller, and an output in communication with the input of the shift register; the feedback function generator includes at least one feedback function.
