Latest Patents

J M Simard holds a patent for a "Digital FSK demodulator with automatic offset cancellation." This invention addresses the challenge of unequal amplitudes in detected mark and space tones within a telephone loop. The demodulator features a digital compensation circuit that continuously monitors the peak amplitudes of digital 0 and digital 1 signals. By averaging these peak amplitudes, the system estimates the offset, which is then subtracted from the output to achieve proper timing signal recovery from the FSK signal. This innovation is crucial for improving the reliability of digital communication.
