Device for demodulating a signal comprising information transmitted by modulating the phase of a carrier

摘要

The device has a generating unit formed by a control clock generator (10), ramp generator (20) and comparator (30) and generating measurement pulse edge corresponding to considered symbol after constant duration. The duration is less than minimal duration of n cycles of a symbol in an input signal (1) that comprises information transmitted by phase shift keying. The unit generates another edge corresponding to considered symbol after null duration following starting of another cycle. A time voltage converter (40) generates an output signal (5), whose voltage varies based on pulse durations.
