Controllable bit stream generator

摘要

A controllable bit stream generator for providing a random bit source with a desired probability. The controllable bit stream generator comprises a digital component which generates a pseudo-random bit sequence, a variable probability conditioner coupled to the digital component and which accepts the pseudo-random bit sequence and outputs a corresponding controlled output, and a register coupled to the variable probability conditioner. The register is utilized to send a control signal to the variable probability conditioner. The controllable bit stream generator creates a random output bit sequence for the controlled output utilizing the variable probability conditioner and the control signal of the register.
