The article focuses on optocouplers which are widely used in industrial automation applications to isolate circuits and their common mode rejection (CMR) performance. Common mode transient immunity or CMR is the ability of a component to reject transient noise signals. The factors involved in defining the CMR are the common mode voltage (VCM) and the rise and fall times of the transient signal (dv/dt).
