Latest Patents

Anatoly Fridland holds a patent for a "Phase-coherent FSK signal demodulator." This invention is a system and process designed for receiving phase-coherent FSK signals that contain both data and clock components. The system comprises multiple subsystems that facilitate data transfer among them. Notably, at least two subsystems can communicate through a transmitter in one and a receiver in the other. The receiver is equipped with a demodulator that effectively separates the data and clock components of the encoded phase-coherent FSK signals.

The clock demodulator features a first transition detector and a 90-degree phase shift circuit, both of which receive the encoded signal. Additionally, a second transition detector processes the output from the phase shift circuit. An OR gate combines the outputs of the first and second transition detectors to generate a four times clock signal. The data component of the phase-coherent FSK signal can be recovered using either of two alternate circuits. The first circuit employs a shift register that analyzes at least four data samples in conjunction with a pair of exclusive OR gates, a NOR gate, and a flip-flop. The alternate data component demodulator includes a first 90-degree phase delay circuit and an inverter, both receiving the encoded data and transmitting it to a first exclusive OR gate. A second 90-degree phase delay circuit processes the output of the first exclusive OR gate, while a second exclusive OR gate receives the outputs from both the second phase delay circuit and the first exclusive OR gate.
