A personalized electronic commerce marketing system wherein in-person sales representatives personally visit potential customers to improve the efficacy of the on-line marketing effort. A processor accesses an instruction that identifies the specific bit of system memory that is to be operated upon, as well as an operation to be performed on the bit. This BSS provides the ability to blindly separate signals in situations where no second-order technique has been found to perform the blind separation satisfactorily, for example, at a low signal-to-noise ratio when the number of sources equals the number of sensors or when the noise is spatially and temporally colored.
