摘要： A transceiver includes a transmission module for generating an output signal, a controller for controlling the transmission module to allow an output signal to have one of a first frequency and a second frequency, a reception module for controlling the controller to allow a control signal to be outputted based on completion information received from the outside. The transmission module outputs an output signal having a first frequency to perform human body communication. When the reception module receives completion information, the transmission module outputs an output signal having a second frequency in response to the control signal in order to perform wireless communication. The first frequency is lower than the second frequency.

摘要： Provided are a random number generating device and a method of operating the same. The random number generating device includes a source detector, a pulse generator, a counter, and a verification circuit. The source detector detects particles emitted from a source to generate a detection signal. The pulse generator generates pulses corresponding to the detected particles, based on the detection signal. The counter measures time intervals among the pulses and generates binary count values respectively corresponding to the time intervals. The verification circuit determines an output of the binary count values, based on the number of 0 values and the number of 1 values included in the binary count values.

摘要： A random number generating device includes a particle detector, a pulse generator, a clock counter, and a random number converter. The particle detector detects particles emitted from a radioactive isotope. The pulse generator generates pulses corresponding to the particles. The clock counter counts the number of clock cycles during time intervals between the pulses and generates a plurality of count values. The random number converter adjusts a clock frequency, based on a minimum value and a maximum value of the plurality of count values and converts a target count value generated depending on the adjusted clock frequency into a random number.
