Cascaded bandpass v-th-law devices

The effect of the n-cascaded bandpass v-th-law devices on the sum of a strong signal and a weak signal is analysed. It is shown that if any of the nonlinear devices is a hard-limiter, the n-cascaded nonlinearities have the same effect as that of a single hard-limiter. If two such cascaded n v-th-law devices (differing in at least one v-th-value) or two complex bandpass nonlinearities are connected in parallel, we obtain the generalised form of a 'power-division' multiplex system which utilises a feed-forward across a limiter technique.
