摘要： A cardiac signal processing apparatus includes: a unit for acquiring, from a heartbeat sensor, cardiac signals relating to heartbeats of a subject; a low-pass filter for allowing passage of those cardiac signals having a first predetermined frequency or lower, among the cardiac signals; higher harmonic noise acquisition unit for acquiring harmonic signals of low-frequency noise by performing high frequency extrapolation on the signals output from the low-pass filter; a high-pass filter for allowing passage of those cardiac signals having a second predetermined frequency or higher, among the cardiac signals; and higher harmonic noise removal unit for removing the harmonic signals of low-frequency noise from the signals output from the high-pass filter. It is thus made possible to remove noise from the cardiac signals and to obtain desirable heartbeat detection characteristics.

摘要： A wireless device includes a baseband unit and front-end units that are provided in individual housings. The baseband unit and the front-end units are connected to each other by wire. A transmitter for synchronization that converts a signal based on a reference clock into a radio signal and transmits the radio signal as a clock synchronization signal is provided in any one of the housings, and receivers for synchronization that receive the signal for the clock synchronization and PLLs that generate a clock synchronized with a reference clock signal which is obtained from the received clock synchronization signal are provided in the housings other than the housing having the transmitter provided therein. In order to simultaneously process a plurality of wireless devices having different symbol rates, it is preferable to provide the transmitter, the receiver, and the PLL for each reference clock.
