DEVELOPMENT AND FABRICATION OF A PROTOTYPE AIRBORNE AND GROUND ENCODING SYSTEM.

Abstract : The development and fabrication of an airborne analog-to-digital converter and a ground based analog to digital converter is described. Both units utilize charge transfer circuits to accomplish the conversion of an analog voltage to a train of pulses which represents a digital number. In the airborne converter, the serial train of pulses is converted into an NRZ format, and this waveform is the digital output. In the ground based converter, the serial train of pulses is fed to a shift register, from which the digital output
