摘要： A high-speed receiver is disclosed herein which is sampled by a reduced swing clock, capable of receiving reduced swing differential input signals. In the disclosed method, a pair of differential input signals (DIN), (DIP) are sampled with a reduced swing clock. The method includes a precharge phase (P1), at which time the clock is low, in which voltages are differentiated at a pair of nodes (X), (Y) based on values of a pair of differential input signals (DIN), (DIP), which are preferably non return to zero reduced swing signals. The differentiated voltages cause at least one regenerated data signal output (DON), or (DOP) to begin transitioning during the precharge phase (P1) in response to a change in the pair of differential input signals.

摘要： A compact lightweight electro-acoustic transducer system for generating high intensity, highly directional audio output. The transducer system can generate acoustic intensity levels that can drive the transmission medium to non-linearity such that highly directional secondary sound also can appear in the audible range allowing direct and parametric sound generation from a single acoustic emission system. The device can be used for both distant and/or high intensity communications to convey information, provide high intensity acoustical targeting and/or disrupt or mask other communications.

摘要： Disclosed is an apparatus for automatic matching and filtering of frequency bandwidths for Internet service using an MATV network, which includes a signal noise processing unit for eliminating noise signals introduced in Internet upstream/downstream signals transmitted from a user terminal, and a CMTS interface for receiving a change of an upstream signal frequency bandwidth of ISP(Internet Service Provider) from CMTS and then changing an upstream signal frequency of the signal noise processing unit. This apparatus may resolve the communication instability caused by the change of upstream frequency since it may automatically cope with the change of various upstream frequency bandwidths of ISPs.

摘要： Data transmission apparatus includes optical transmitters (14a, 14b) coupled to an optical link (10). A FEC coder (40) is coupled to the input of transmitter (14b'). A first signal (12a) having a first rate is provided to the first transmitter, and a second signal (12b) having a higher information rate than the first signal, while simultaneously enabling the respective output power levels of the amplifiers (18a, 18b). The transmission apparatus achieves higher transmission capacity while retaining compatibility with pre-existing fiber spans and amplifier nodes. An optical transmission system incorporates a transmitter (70) and a receiver (72) having certain transmission characteristics, such as output power level, decision threshold level, etc., that are adjustable in response to BER. A BER estimator (74) is provided at the receiving end of the link. The estimator estimates the BER of the received signal, and provides BER to the receiver, and/or transmitter, and/or optical link, based on the estimated BER, to optimize performance.

摘要： Method of reducing transmission power across a loop (110) in a discrete multitone communication system (100). A first signal to noise ratio (SNR) is estimated (302) for a signal transmitted across the loop. A second SNR is estimated (304) for a signal across the loop, the second SNR signal being estimated exclusive of a predetermined portion of the first SNR. A power cutback scaling factor is determined (306) in accordance with the first SNR, the second SNR, and a predefined maximum SNR degradation amount. The transmission power is scaled (308) in accordance with said scaling factor for reducing said transmission power. In such a manner, fine gains are computed such that the transmit power is reduced without significantly affecting the achieved data rate.

摘要： A wiring apparatus for reducing electromagnetic interference between conductive wires is provided. Wire pairs are incorporated into rigid or flexible printed circuits to precisely control loop alignment and phase differences. This precise alignment helps to cancel radiated electromagnetic fields and reduce voltage polarities induced in nearby wires. In one embodiment, a pair of parallel wires is aligned parallel to a second, twisted pair of wires. In another embodiment, two twisted pairs of wires, with identical loop lengths, are aligned parallel to each other and offset by exactly one half loop length. In a third embodiment, two twisted pairs of wires are aligned parallel to each other, in which one pair has a loop length that is an integer ratio of the other pair.
