Minimisation of MBS switch-on transient by linear prediction

Binary test signals as information machine signals have advantages over other test signals in their ease of generation and application by microcomputer to a control system. With many multifrequency binary sequences (MBS), not only the amplitude but also the sequence finite bit length and the signal processing adhere to a binary format. These maximum entropy test signals offer the advantage of zero offset with a wide variety of power spectral distribution. For the case of a binary signal that meanders equally about its starting value, there is developed a method of at least minimising, if not eliminating, the effect of switch-on transients upon the frequency response estimates. By using a suitable asymmetrical form of the binary generating code or an asymmetrical meander, an immediate online identification of slower real-time industrial processes may be achieved
