Abstract
An analog direct current to one MHz information channel is provided, with high acccuracy and 10K volt input-output isolation. The information channel has a voltage to current converter which receives the analog input signal, and whose output is modulated by a square wave generator and provided to a center tap of the primary winding of a transformer. On the output side, the secondary winding of the transformer provides the signal to a precision rectifier which recovers the analog input signal.
