Abstract : The patent describes a time sharing demodulation system for radiometers using a pair of parallel field effect transistor channels, one of which is preceded by an inverter with the pair of channels being followed by an integrator. The field effect transistors are driven by a pair of drive signals each having a periodic square wave with the repetition frequency of a single time shared radiometer signal and having a pulse width equal to a time shared interval. The pair of drive signals are 180 degrees out of phase with each other.
