  • Patent number: 7305027
    Abstract: This invention discloses a receiver and a signal compensation method therefor. An adaptive equalizer and a baseline wander compensator are provided on the front end of the receiver to improve the quality of output signals. The signal compensation method enables the adaptive equalizer to use a long T as its observation unit when the transmission cable is idle, and enables the baseline wander compensator for operation and controls both the adaptive equalizer and the baseline wander compensator to use a short T as its observation unit when the transmission cable is transmitting data signals. The disclosed adaptive equalizer can achieve its optimal processing effects, and the efficiency of the baseline wander compensator can be increased.

  • Patent number: 7136421
    Abstract: A signal compensation circuit and associated method dynamically compensate for signal baseline wandering in a transmission line. The compensation circuit has a detection circuit and a correction circuit. The detection circuit first compares a transmission signal with a reference level and generates a comparison result. The correction circuit then corrects the transmission signal according to the comparison result. The compensation circuit can adjust its compensation over time based on the quality of the transmission signal.

  • Patent number: 7130274
    Abstract: A method and associated detecting circuitss for detecting and correcting a connection polarity of a network transmission line include two network clients and a network transmission line. One network client utilizes a detecting circuit to count and compare the number of signal pulses at the receiving and transmitting ports to determine if the connection polarity is correct or inverted. The detecting circuit can switch the connection polarity if required to correct it.

  • Patent number: 7103123
    Abstract: This invention discloses an adaptive equalizer disposed on the front end of a receiver to improve the quality of a transmission signal comprising a data signal from a transmission cable. The signal compensation of the adaptive equalizer uses a long T as its observation unit when the transmission cable is idle, and uses a short T as its observation unit when the transmission cable is transmitting data signals. This invention further discloses a baseline wander compensator worked with the adaptive equalizer during the transmitting data period of the transmission cable. The disclosed adaptive equalizer can achieve its optimal processing effects.

  • Patent number: 6385273
    Abstract: A testing device for checking a clock signal generated by a clock pulse generating circuit. The clock pulse generating circuit outputs a clock signal and a multiplied clock second signal. The testing device includes a reset circuit, a dividing unit and a mask circuit. The reset circuit receives a first reset signal and the clock signal and then generates a second reset signal synchronous with the clock signal. The second reset signal controls the dividing unit and the mask circuit. Inside the dividing unit, the multiplied clock signal is divided by an integral multiple to produce a divided clock signal. The divided clock signal is then passed to the mask circuit where uncertain portions of the third signal are blanketed to produce a masked clock signal. The masked clock signal is sent to a tester where cycle width of the masked clock signal is measured and first reset signal is sent to the reset circuit.
