摘要:
A signal transmission apparatus of the invention comprises: a correlator 12 for shaping a spectrum of a signal; and a precoder 12 disposed on a previous stage of the correlator and including an adder which subtracts an output signal of a feedback filter from an input signal, a modulo arithmetic unit which inputs an output signal of the adder and executes modulo arithmetic operation, and the feedback filter which inputs an output signal of the modulo arithmetic unit and is provided with a transfer function obtained by subtracting 1 from a transfer function of the correlator. The correlator may be IIR filter means having a desired notch characteristic. By disposing a correlator which can freely shape a transmission signal spectrum containing a deep notch and suppress only a specified band on a receiving side, the suppression of an external noise can also be realized.
摘要:
A serial-parallel converter/encoder unit 11 inputs a transmission symbol data at a transmission symbol rate that is one-Nth of a base-point symbol rate. A precoder/collator 13 creates a transmission symbol waveform at the base-point symbol rate. The transmission symbol waveform becomes a transmission signal after passing through a roll-off filter 14 with a band corresponding to the base-point symbol rate and a modulator 15. A reception signal demodulated by a demodulator 33 is input to a fractionally-spaced equalizer 38 that operates at the base-point symbol rate and is forcibly equalized at the transmission symbol rate by using a reference signal. A level of a signal output from the fractionally-spaced equalizer 38 at the transmission symbol rate is determined by a level determining unit 39 and becomes a reception symbol data by a sawtooth-function output unit 40.

Systems and methods are provided for a flexible and scalable operating system achieving a fast boot. A computing system is described that includes a reserved static object memory configured to store predefined static threads, and a secure kernel configured to be executed in a fast boot mode. The secure kernel further may be configured to chain the static threads to a secure kernel thread queue stored in a secure kernel work memory, and to create temporary threads in the secure kernel work memory during the fast boot mode. The computing system may include a main kernel configured to be initialized by creating dynamic threads in a main kernel work memory during the fast boot mode. The main kernel may be configured to chain the static threads to a main kernel thread queue, and to assume control of the static threads from the secure kernel.

The precision of crack-propagation prediction is improved by taking into consideration a variation in the error due to inspectors and inspection methods. There is provided a crack-propagation prediction method including a correlation-information preparing step of measuring the length of a crack initiated in a test object by a plurality of inspectors and/or a plurality of inspection methods and obtaining correlation information between data acquired through the measurement and the condition of an actual crack; a crack-length estimating step of estimating the actual length of the crack initiated in an inspection target on the basis of the crack length measured by an inspector during inspection of the inspection target and the correlation information; and a crack-propagation-curve estimating step of estimating a crack-propagation curve of the inspection target originating from the crack length estimated in the crack-length estimating step.

The present invention provides a fan that has a fan motor and two signal lines including a number-of-rotations switching control signal line and a rotational state outputting signal line, makes the fan motor rotate at a number of rotations determined by a number-of-rotations switching control signal input via the number-of-rotations switching control signal line, outputs the rotational state of the fan motor via the rotational state outputting signal line, and can provide notification of detail data without increasing the number of signal lines. The fan retains data in the data storage section in a non-volatile manner and outputs the data via the conventionally existing rotational state outputting signal line.
