In this paper, a novel Pseudo-random (PN) based wideband chaotic signal generator is proposed. The PN code generated has been used to simulate a digitally controllable variable resistor. The value of resistor and hence the frequency of chaotic signal generator is made vary by incoming PN code. The results of the implemented scheme used to generate wide range of frequencies of random nature are incorporated in the paper.
