1 Receiver, sender, method for retrieving an additional datum from a signal and method for transmitting a datum and an additional datum in a signal US14933349 2015-11-05 US09882579B2 2018-01-30 Dirk Hammerschmidt
A receiver includes a receiver circuit to receive a first transition in a first direction, a second transition in a second, different direction after the first transition and a third transition in the first transition after the second transition of a signal. A first time period between the first and third transitions is indicative of a datum to be received. The receiver circuit is also configured to determine a second time period between the first transition and a second transition and to determine an additional datum to be received based at least on the determined second time period between the first and second transitions. Using the determined second time period allows for more information to be received in a reliable manner.

An output data generating unit sequentially outputs m output data obtained by the computation processing unit according to a second frequency.

6 APPARATUS AND METHOD FOR CARRIER STATE MODULATION US14592077 2015-01-08 US20150124905A1 2015-05-07 William A. GANTER
A carrier state modulator system is described in which a stream of digital data bits is encoded by modulating the amplitude or phase of a carrier wave. A transmitter directly modulates the amplitude or phase of a selected number of cycles of the carrier in accordance with the state of each digital data bit. This method of direct generation of an amplitude or phase modulated carrier wave differs from mixing a phase amplitude baseband modulation onto a higher carrier frequency.

8 Encoder signal analysis system for high-resolution position measurement US890741 1997-07-11 US5933106A 1999-08-03 Gang He; Harry A. Atwater
A signal analysis system for processing quadrature analog waveforms from an encoder. High-resolution position measurements for external measurement devices are obtained. A hardware component receives the quadrature analog signals from the encoder and processes these signals to generate low and high-resolution waveforms. These waveforms are then further processed and sent as first and second data streams to a computational component of the signal analysis system. The absolute phase angle (.THETA.) of the encoder's analog signal is determined by processing the data streams with the computational component. .THETA. is compared to a series of calibration factors to determine the position of the translating component of the external measurement device.

A method and apparatus for compression of digital and analog data utilizing an anamorphic spectrum transformation to warp an analog or digital signal to provide time-bandwidth compression after sampling is performed on the warped signal. The anamorphic spectrum transformation performs reallocating samples to assign more samples to fine features with high frequency waveform portions and fewer samples to coarse features with low frequency portions of the analog temporal signal, resulting in shorter record length and fewer number of samples.

The value of the encoded digital data bit of the modulated signal is determined from the phase score.

PURPOSE: A data coding method using frequency transition pattern conversion is provided to attain infinitely great compression rate without bringing about signal deterioration or loss. CONSTITUTION: In a data coding method using frequency transition pattern conversion, source data in the form of K rectangular waves is transferred to 2k pulse frequency so that the parameter of the source data is pattern-converted into simple parameter of the pulse frequency, to thereby simplify the data. The energy spectrum density and bit rate of the original source data are reduced to compress the data. The compressed data is considered as one block and the block is connected in series or parallel so that the compressed data is further compressed. In case of decoding, a frequency previously assigned in the compression procedure is detected to decode the original source data. The pattern conversion is considered as an individual block and decoding processes as many as the number of blocks connected in series or parallel in the compression procedure are carried out to decode the original source data.
