摘要: A method, algorithm, circuits, and/or systems for amplitude shift keying (ASK) modulation are disclosed. In one embodiment, a sampling demodulator includes comparator configured to compare an ASK modulated input predetermined voltage level and provide comparison result, pulse stretcher with sampler sample the result plurality of times each cycles generate bit stream digital logic determine value data in from stream, filter output logic, thereby providing demodulated signal.
