Analog signal to discrete time interval converter information
Not to be confused with ASDIC.
An analog signal to discrete time interval converter (ASDTIC) is a specialized kind of an analog-to-digital converter, which converts the analog input signal (e.g. voltage or current) to time intervals between pulses.
This conversion is a type of Pulse-width modulation (PWM). The origin of the term ASDTIC lies with NASA around 1970.[1]
ASDTIC were used in the control of DC-DC converters.[2] For use in space-rated systems, reliable hybrid circuits were developed to implement the ASDTIC function.[3]
